Merge git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers.git
Stephen Rothwell reported quite a few conflicts in iwlwifi between
wireless-drivers and wireless-drivers-next. To avoid any problems later in
other trees merge w-d to w-d-next to fix those conflicts early.

+Also called AXI 1G/2.5G Ethernet Subsystem, the xilinx axi ethernet IP core
+provides connectivity to an external ethernet PHY supporting different
+interfaces: MII, GMII, RGMII, SGMII, 1000BaseX. It also includes two
+segments of memory for buffering TX and RX, as well as the capability of
+offloading TX/RX checksum calculation off the processor.
+
+Management configuration is done through the AXI interface, while payload is
+sent and received through means of an AXI DMA controller. This driver
+includes the DMA driver code, so this driver is incompatible with AXI DMA
+driver.

+- reg : Address and length of the IO space.
+- interrupts : Should be a list of two interrupt, TX and RX.
+- phy-handle : Should point to the external phy device.

Digital TV (DVB) devices
------------------------
+Digital TV devices are implemented by several different drivers:
+
+- A bridge driver that is responsible to talk with the bus where the other
+ devices are connected (PCI, USB, SPI), bind to the other drivers and
+ implement the digital demux logic (either in software or in hardware);
+
+- Frontend drivers that are usually implemented as two separate drivers:
+
+ - A tuner driver that implements the logic with commands the part of the
+ hardware with is reponsible to tune into a digital TV transponder or
+ physical channel. The output of a tuner is usually a baseband or
+ Intermediate Frequency (IF) signal;
+
+ - A demodulator driver (a.k.a "demod") that implements the logic with
+ commands the digital TV decoding hardware. The output of a demod is
+ a digital stream, with multiple audio, video and data channels typically
+ multiplexed using MPEG Transport Stream [#f1]_.
+
+On most hardware, the frontend drivers talk with the bridge driver using an
+I2C bus.

+Digital TV Frontend statistics
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Introduction
+^^^^^^^^^^^^
+
+Digital TV frontends provide a range of
+:ref:`statistics <frontend-stat-properties>` meant to help tuning the device
+and measuring the quality of service.
+
+For each statistics measurement, the driver should set the type of scale used,
+or ``FE_SCALE_NOT_AVAILABLE`` if the statistics is not available on a given
+time. Drivers should also provide the number of statistics for each type.
+that's usually 1 for most video standards [#f2]_.
+
+Drivers should initialize each statistic counters with length and
+scale at its init code. For example, if the frontend provides signal
+strength, it should have, on its init code::
+
+ struct dtv_frontend_properties *c = &state->fe.dtv_property_cache;
+
+ c->strength.len = 1;
+ c->strength.stat[0].scale = FE_SCALE_NOT_AVAILABLE;
+
+And, when the statistics got updated, set the scale::
+
+ c->strength.stat[0].scale = FE_SCALE_DECIBEL;
+ c->strength.stat[0].uvalue = strength;
+
+.. [#f2] For ISDB-T, it may provide both a global statistics and a per-layer
+ set of statistics. On such cases, len should be equal to 4. The first
+ value corresponds to the global stat; the other ones to each layer, e. g.:
+
+ - c->cnr.stat[0] for global S/N carrier ratio,
+ - c->cnr.stat[1] for Layer A S/N carrier ratio,
+ - c->cnr.stat[2] for layer B S/N carrier ratio,
+ - c->cnr.stat[3] for layer C S/N carrier ratio.
+
+.. note:: Please prefer to use ``FE_SCALE_DECIBEL`` instead of
+ ``FE_SCALE_RELATIVE`` for signal strength and CNR measurements.
+
+Groups of statistics
+^^^^^^^^^^^^^^^^^^^^
+
+There are several groups of statistics currently supported:
+
+Signal strength (:ref:`DTV-STAT-SIGNAL-STRENGTH`)
+ - Measures the signal strength level at the analog part of the tuner or
+ demod.
+
+ - Typically obtained from the gain applied to the tuner and/or frontend
+ in order to detect the carrier. When no carrier is detected, the gain is
+ at the maximum value (so, strength is on its minimal).
+
+ - As the gain is visible through the set of registers that adjust the gain,
+ typically, this statistics is always available [#f3]_.
+
+ - Drivers should try to make it available all the times, as this statistics
+ can be used when adjusting an antenna position and to check for troubles
+ at the cabling.
+
+ .. [#f3] On a few devices, the gain keeps floating if no carrier.
+ On such devices, strength report should check first if carrier is
+ detected at the tuner (``FE_HAS_CARRIER``, see :c:type:`fe_status`),
+ and otherwise return the lowest possible value.
+
+Carrier Signal to Noise ratio (:ref:`DTV-STAT-CNR`)
+ - Signal to Noise ratio for the main carrier.
+
+ - Signal to Noise measurement depends on the device. On some hardware, is
+ available when the main carrier is detected. On those hardware, CNR
+ measurement usually comes from the tuner (e. g. after ``FE_HAS_CARRIER``,
+ see :c:type:`fe_status`).
+
+ On other devices, it requires inner FEC decoding,
+ as the frontend measures it indirectly from other parameters (e. g. after
+ ``FE_HAS_VITERBI``, see :c:type:`fe_status`).
+
+ Having it available after inner FEC is more common.
+
+Bit counts post-FEC (:ref:`DTV-STAT-POST-ERROR-BIT-COUNT` and :ref:`DTV-STAT-POST-TOTAL-BIT-COUNT`)
+ - Those counters measure the number of bits and bit errors errors after
+ the forward error correction (FEC) on the inner coding block
+ (after Viterbi, LDPC or other inner code).
+
+ - Due to its nature, those statistics depend on full coding lock
+ (e. g. after ``FE_HAS_SYNC`` or after ``FE_HAS_LOCK``,
+ see :c:type:`fe_status`).
+
+Bit counts pre-FEC (:ref:`DTV-STAT-PRE-ERROR-BIT-COUNT` and :ref:`DTV-STAT-PRE-TOTAL-BIT-COUNT`)
+ - Those counters measure the number of bits and bit errors errors before
+ the forward error correction (FEC) on the inner coding block
+ (before Viterbi, LDPC or other inner code).
+
+ - Not all frontends provide this kind of statistics.
+
+ - Due to its nature, those statistics depend on inner coding lock (e. g.
+ after ``FE_HAS_VITERBI``, see :c:type:`fe_status`).
+
+Block counts (:ref:`DTV-STAT-ERROR-BLOCK-COUNT` and :ref:`DTV-STAT-TOTAL-BLOCK-COUNT`)
+ - Those counters measure the number of blocks and block errors errors after
+ the forward error correction (FEC) on the inner coding block
+ (before Viterbi, LDPC or other inner code).
+
+ - Due to its nature, those statistics depend on full coding lock
+ (e. g. after ``FE_HAS_SYNC`` or after
+ ``FE_HAS_LOCK``, see :c:type:`fe_status`).
+
+.. note:: All counters should be monotonically increased as they're
+ collected from the hardware.
+
+A typical example of the logic that handle status and statistics is::
+
+ static int foo_get_status_and_stats(struct dvb_frontend *fe)
+ {
+ struct foo_state *state = fe->demodulator_priv;
+ struct dtv_frontend_properties *c = &fe->dtv_property_cache;
+
+ int rc;
+ enum fe_status *status;
+
+ /* Both status and strength are always available */
+ rc = foo_read_status(fe, &status);
+ if (rc < 0)
+ return rc;
+
+ rc = foo_read_strength(fe);
+ if (rc < 0)
+ return rc;
+
+ /* Check if CNR is available */
+ if (!(fe->status & FE_HAS_CARRIER))
+ return 0;
+
+ rc = foo_read_cnr(fe);
+ if (rc < 0)
+ return rc;
+
+ /* Check if pre-BER stats are available */
+ if (!(fe->status & FE_HAS_VITERBI))
+ return 0;
+
+ rc = foo_get_pre_ber(fe);
+ if (rc < 0)
+ return rc;
+
+ /* Check if post-BER stats are available */
+ if (!(fe->status & FE_HAS_SYNC))
+ return 0;
+
+ rc = foo_get_post_ber(fe);
+ if (rc < 0)
+ return rc;
+ }
+
+ static const struct dvb_frontend_ops ops = {
+ /* ... */
+ .read_status = foo_get_status_and_stats,
+ };
+
+Statistics collect
+^^^^^^^^^^^^^^^^^^
+
+On almost all frontend hardware, the bit and byte counts are stored by
+the hardware after a certain amount of time or after the total bit/block
+counter reaches a certain value (usually programable), for example, on
+every 1000 ms or after receiving 1,000,000 bits.
+
+So, if you read the registers too soon, you'll end by reading the same
+value as in the previous reading, causing the monotonic value to be
+incremented too often.
+
+Drivers should take the responsibility to avoid too often reads. That
+can be done using two approaches:
+
+if the driver have a bit that indicates when a collected data is ready
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+
+Driver should check such bit before making the statistics available.
+
+An example of such behavior can be found at this code snippet (adapted
+from mb86a20s driver's logic)::
+
+ static int foo_get_pre_ber(struct dvb_frontend *fe)
+ {
+ struct foo_state *state = fe->demodulator_priv;
+ struct dtv_frontend_properties *c = &fe->dtv_property_cache;
+ int rc, bit_error;
+
+ /* Check if the BER measures are already available */
+ rc = foo_read_u8(state, 0x54);
+ if (rc < 0)
+ return rc;
+
+ if (!rc)
+ return 0;
+
+ /* Read Bit Error Count */
+ bit_error = foo_read_u32(state, 0x55);
+ if (bit_error < 0)
+ return bit_error;
+
+ /* Read Total Bit Count */
+ rc = foo_read_u32(state, 0x51);
+ if (rc < 0)
+ return rc;
+
+ c->pre_bit_error.stat[0].scale = FE_SCALE_COUNTER;
+ c->pre_bit_error.stat[0].uvalue += bit_error;
+ c->pre_bit_count.stat[0].scale = FE_SCALE_COUNTER;
+ c->pre_bit_count.stat[0].uvalue += rc;
+
+ return 0;
+ }
+
+If the driver doesn't provide a statistics available check bit
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+
+A few devices, however, may not provide a way to check if the stats are
+available (or the way to check it is unknown). They may not even provide
+a way to directly read the total number of bits or blocks.
+
+On those devices, the driver need to ensure that it won't be reading from
+the register too often and/or estimate the total number of bits/blocks.
+
+On such drivers, a typical routine to get statistics would be like
+(adapted from dib8000 driver's logic)::
+
+ struct foo_state {
+ /* ... */
+
+ unsigned long per_jiffies_stats;
+ }
+
+ static int foo_get_pre_ber(struct dvb_frontend *fe)
+ {
+ struct foo_state *state = fe->demodulator_priv;
+ struct dtv_frontend_properties *c = &fe->dtv_property_cache;
+ int rc, bit_error;
+ u64 bits;
+
+ /* Check if time for stats was elapsed */
+ if (!time_after(jiffies, state->per_jiffies_stats))
+ return 0;
+
+ /* Next stat should be collected in 1000 ms */
+ state->per_jiffies_stats = jiffies + msecs_to_jiffies(1000);
+
+ /* Read Bit Error Count */
+ bit_error = foo_read_u32(state, 0x55);
+ if (bit_error < 0)
+ return bit_error;
+
+ /*
+ * On this particular frontend, there's no register that
+ * would provide the number of bits per 1000ms sample. So,
+ * some function would calculate it based on DTV properties
+ */
+ bits = get_number_of_bits_per_1000ms(fe);
+
+ c->pre_bit_error.stat[0].scale = FE_SCALE_COUNTER;
+ c->pre_bit_error.stat[0].uvalue += bit_error;
+ c->pre_bit_count.stat[0].scale = FE_SCALE_COUNTER;
+ c->pre_bit_count.stat[0].uvalue += bits;
+
+ return 0;
+ }
+
+Please notice that, on both cases, we're getting the statistics using the
+:c:type:`dvb_frontend_ops` ``.read_status`` callback. The rationale is that
+the frontend core will automatically call this function periodically
+(usually, 3 times per second, when the frontend is locked).
+
+That warrants that we won't miss to collect a counter and increment the
+monotonic stats at the right time.

+==========
+
+Batman advanced is a new approach to wireless networking which does no longer
+operate on the IP basis. Unlike the batman daemon, which exchanges information
+using UDP packets and sets routing tables, batman-advanced operates on ISO/OSI
+Layer 2 only and uses and routes (or better: bridges) Ethernet Frames. It
+emulates a virtual network switch of all nodes participating. Therefore all
+nodes appear to be link local, thus all higher operating protocols won't be
+affected by any changes within the network. You can run almost any protocol
+above batman advanced, prominent examples are: IPv4, IPv6, DHCP, IPX.
+
+Batman advanced was implemented as a Linux kernel driver to reduce the overhead
+to a minimum. It does not depend on any (other) network driver, and can be used
+on wifi as well as ethernet lan, vpn, etc ... (anything with ethernet-style
+layer 2).
+
+
+Configuration
+=============
+
+Load the batman-adv module into your kernel::
+
+ $ insmod batman-adv.ko
+
+The module is now waiting for activation. You must add some interfaces on which
+batman can operate. After loading the module batman advanced will scan your
+systems interfaces to search for compatible interfaces. Once found, it will
+create subfolders in the ``/sys`` directories of each supported interface,
+e.g.::
+
+ $ ls /sys/class/net/eth0/batman_adv/
+ elp_interval iface_status mesh_iface throughput_override
+
+If an interface does not have the ``batman_adv`` subfolder, it probably is not
+supported. Not supported interfaces are: loopback, non-ethernet and batman's
+own interfaces.
+
+Note: After the module was loaded it will continuously watch for new
+interfaces to verify the compatibility. There is no need to reload the module
+if you plug your USB wifi adapter into your machine after batman advanced was
+initially loaded.
+
+The batman-adv soft-interface can be created using the iproute2 tool ``ip``::
+
+ $ ip link add name bat0 type batadv
+
+To activate a given interface simply attach it to the ``bat0`` interface::
+
+ $ ip link set dev eth0 master bat0
+
+Repeat this step for all interfaces you wish to add. Now batman starts
+using/broadcasting on this/these interface(s).
+
+By reading the "iface_status" file you can check its status::
+
+ $ cat /sys/class/net/eth0/batman_adv/iface_status
+ active
+
+To deactivate an interface you have to detach it from the "bat0" interface::
+
+ $ ip link set dev eth0 nomaster
+
+
+All mesh wide settings can be found in batman's own interface folder::
+
+ $ ls /sys/class/net/bat0/mesh/
+ aggregated_ogms fragmentation isolation_mark routing_algo
+ ap_isolation gw_bandwidth log_level vlan0
+ bonding gw_mode multicast_mode
+ bridge_loop_avoidance gw_sel_class network_coding
+ distributed_arp_table hop_penalty orig_interval
+
+There is a special folder for debugging information::
+
+ $ ls /sys/kernel/debug/batman_adv/bat0/
+ bla_backbone_table log neighbors transtable_local
+ bla_claim_table mcast_flags originators
+ dat_cache nc socket
+ gateways nc_nodes transtable_global
+
+Some of the files contain all sort of status information regarding the mesh
+network. For example, you can view the table of originators (mesh
+participants) with::
+
+ $ cat /sys/kernel/debug/batman_adv/bat0/originators
+
+Other files allow to change batman's behaviour to better fit your requirements.
+For instance, you can check the current originator interval (value in
+milliseconds which determines how often batman sends its broadcast packets)::
+
+ $ cat /sys/class/net/bat0/mesh/orig_interval
+ 1000
+
+and also change its value::
+
+ $ echo 3000 > /sys/class/net/bat0/mesh/orig_interval
+
+In very mobile scenarios, you might want to adjust the originator interval to a
+lower value. This will make the mesh more responsive to topology changes, but
+will also increase the overhead.
+
+
+Usage
+=====
+
+To make use of your newly created mesh, batman advanced provides a new
+interface "bat0" which you should use from this point on. All interfaces added
+to batman advanced are not relevant any longer because batman handles them for
+you. Basically, one "hands over" the data by using the batman interface and
+batman will make sure it reaches its destination.
+
+The "bat0" interface can be used like any other regular interface. It needs an
+IP address which can be either statically configured or dynamically (by using
+DHCP or similar services)::
+
+ NodeA: ip link set up dev bat0
+ NodeA: ip addr add 192.168.0.1/24 dev bat0
+
+ NodeB: ip link set up dev bat0
+ NodeB: ip addr add 192.168.0.2/24 dev bat0
+ NodeB: ping 192.168.0.1
+
+Note: In order to avoid problems remove all IP addresses previously assigned to
+interfaces now used by batman advanced, e.g.::
+
+ $ ip addr flush dev eth0
+
+
+Logging/Debugging
+=================
+
+All error messages, warnings and information messages are sent to the kernel
+log. Depending on your operating system distribution this can be read in one of
+a number of ways. Try using the commands: ``dmesg``, ``logread``, or looking in
+the files ``/var/log/kern.log`` or ``/var/log/syslog``. All batman-adv messages
+are prefixed with "batman-adv:" So to see just these messages try::
+
+ $ dmesg | grep batman-adv
+
+When investigating problems with your mesh network, it is sometimes necessary to
+see more detail debug messages. This must be enabled when compiling the
+batman-adv module. When building batman-adv as part of kernel, use "make
+menuconfig" and enable the option ``B.A.T.M.A.N. debugging``
+(``CONFIG_BATMAN_ADV_DEBUG=y``).
+
+Those additional debug messages can be accessed using a special file in
+debugfs::
+
+ $ cat /sys/kernel/debug/batman_adv/bat0/log
+
+The additional debug output is by default disabled. It can be enabled during
+run time. Following log_levels are defined:
+
+.. flat-table::
+
+ * - 0
+ - All debug output disabled
+ * - 1
+ - Enable messages related to routing / flooding / broadcasting
+ * - 2
+ - Enable messages related to route added / changed / deleted
+ * - 4
+ - Enable messages related to translation table operations
+ * - 8
+ - Enable messages related to bridge loop avoidance
+ * - 16
+ - Enable messages related to DAT, ARP snooping and parsing
+ * - 32
+ - Enable messages related to network coding
+ * - 64
+ - Enable messages related to multicast
+ * - 128
+ - Enable messages related to throughput meter
+ * - 255
+ - Enable all messages
+
+The debug output can be changed at runtime using the file
+``/sys/class/net/bat0/mesh/log_level``. e.g.::
+
+ $ echo 6 > /sys/class/net/bat0/mesh/log_level
+
+will enable debug messages for when routes change.
+
+Counters for different types of packets entering and leaving the batman-adv
+module are available through ethtool::
+
+ $ ethtool --statistics bat0
+
+
+batctl
+======
+
+As batman advanced operates on layer 2, all hosts participating in the virtual
+switch are completely transparent for all protocols above layer 2. Therefore
+the common diagnosis tools do not work as expected. To overcome these problems,
+batctl was created. At the moment the batctl contains ping, traceroute, tcpdump
+and interfaces to the kernel module settings.
+
+For more information, please see the manpage (``man batctl``).

-BATMAN-ADV
-----------
-
-Batman advanced is a new approach to wireless networking which
-does no longer operate on the IP basis. Unlike the batman daemon,
-which exchanges information using UDP packets and sets routing
-tables, batman-advanced operates on ISO/OSI Layer 2 only and uses
-and routes (or better: bridges) Ethernet Frames. It emulates a
-virtual network switch of all nodes participating. Therefore all
-nodes appear to be link local, thus all higher operating proto-
-cols won't be affected by any changes within the network. You can
-run almost any protocol above batman advanced, prominent examples
-are: IPv4, IPv6, DHCP, IPX.

+Hyper-V network driver
+======================
+
+Compatibility
+=============
+
+This driver is compatible with Windows Server 2012 R2, 2016 and
+Windows 10.
+
+Features
+========
+
+ Checksum offload
+ ----------------
+ The netvsc driver supports checksum offload as long as the
+ Hyper-V host version does. Windows Server 2016 and Azure
+ support checksum offload for TCP and UDP for both IPv4 and
+ IPv6. Windows Server 2012 only supports checksum offload for TCP.
+
+ Receive Side Scaling
+ --------------------
+ Hyper-V supports receive side scaling. For TCP, packets are
+ distributed among available queues based on IP address and port
+ number. Current versions of Hyper-V host, only distribute UDP
+ packets based on the IP source and destination address.
+ The port number is not used as part of the hash value for UDP.
+ Fragmented IP packets are not distributed between queues;
+ all fragmented packets arrive on the first channel.
+
+ Generic Receive Offload, aka GRO
+ --------------------------------
+ The driver supports GRO and it is enabled by default. GRO coalesces
+ like packets and significantly reduces CPU usage under heavy Rx
+ load.
+
+ SR-IOV support
+ --------------
+ Hyper-V supports SR-IOV as a hardware acceleration option. If SR-IOV
+ is enabled in both the vSwitch and the guest configuration, then the
+ Virtual Function (VF) device is passed to the guest as a PCI
+ device. In this case, both a synthetic (netvsc) and VF device are
+ visible in the guest OS and both NIC's have the same MAC address.
+
+ The VF is enslaved by netvsc device. The netvsc driver will transparently
+ switch the data path to the VF when it is available and up.
+ Network state (addresses, firewall, etc) should be applied only to the
+ netvsc device; the slave device should not be accessed directly in
+ most cases. The exceptions are if some special queue discipline or
+ flow direction is desired, these should be applied directly to the
+ VF slave device.
+
+ Receive Buffer
+ --------------
+ Packets are received into a receive area which is created when device
+ is probed. The receive area is broken into MTU sized chunks and each may
+ contain one or more packets. The number of receive sections may be changed
+ via ethtool Rx ring parameters.
+
+ There is a similar send buffer which is used to aggregate packets for sending.
+ The send area is broken into chunks of 6144 bytes, each of section may
+ contain one or more packets. The send buffer is an optimization, the driver
+ will use slower method to handle very large packets or if the send buffer
+ area is exhausted.

-Stream Parser
--------------
+Stream Parser (strparser)
+
+Introduction
+============
The stream parser (strparser) is a utility that parses messages of an
-application layer protocol running over a TCP connection. The stream
+application layer protocol running over a data stream. The stream
parser works in conjunction with an upper layer in the kernel to provide
kernel support for application layer messages. For instance, Kernel
Connection Multiplexor (KCM) uses the Stream Parser to parse messages
using a BPF program.
+The strparser works in one of two modes: receive callback or general
+mode.
+
+In receive callback mode, the strparser is called from the data_ready
+callback of a TCP socket. Messages are parsed and delivered as they are
+received on the socket.
+
+In general mode, a sequence of skbs are fed to strparser from an
+outside source. Message are parsed and delivered as the sequence is
+processed. This modes allows strparser to be applied to arbitrary
+streams of data.
+
Interface
----------
+=========
The API includes a context structure, a set of callbacks, utility
-functions, and a data_ready function. The callbacks include
-a parse_msg function that is called to perform parsing (e.g.
-BPF parsing in case of KCM), and a rcv_msg function that is called

+ strparser that is allocated by the upper layer. sk is the TCP
+ socket associated with the stream parser for use with receive
+ callback mode; in general mode this is set to NULL. Callbacks
+ are called by the stream parser (the callbacks are listed below).
+
+void strp_pause(struct strparser *strp)
+
+ Temporarily pause a stream parser. Message parsing is suspended
+ and no new messages are delivered to the upper layer.
+
+void strp_pause(struct strparser *strp)
+
+ Unpause a paused stream parser.
+
+void strp_stop(struct strparser *strp);
+
+ strp_stop is called to completely stop stream parser operations.
+ This is called internally when the stream parser encounters an
+ error, and it is called from the upper layer to stop parsing
+ operations.
+
+void strp_done(struct strparser *strp);
+
+ strp_done is called to release any resources held by the stream
+ parser instance. This must be called after the stream processor
+ has been stopped.
+
+int strp_process(struct strparser *strp, struct sk_buff *orig_skb,
+ unsigned int orig_offset, size_t orig_len,
+ size_t max_msg_size, long timeo)
+
+ strp_process is called in general mode for a stream parser to
+ parse an sk_buff. The number of bytes processed or a negative
+ error number is returned. Note that strp_process does not
+ consume the sk_buff. max_msg_size is maximum size the stream
+ parser will parse. timeo is timeout for completing a message.
+
+void strp_data_ready(struct strparser *strp);
+
+ The upper layer calls strp_tcp_data_ready when data is ready on
+ the lower socket for strparser to process. This should be called
+ from a data_ready callback that is set on the socket. Note that
+ maximum messages size is the limit of the receive socket
+ buffer and message timeout is the receive timeout for the socket.
+
+void strp_check_rcv(struct strparser *strp);
+
+ strp_check_rcv is called to check for new messages on the socket.
+ This is normally called at initialization of a stream parser
+ instance or after strp_unpause.
Callbacks

+=========
-There are four callbacks:

This function is called when stream parser encounters an error

-Functions
----------
-
-The upper layer calls strp_tcp_data_ready when data is ready on the lower
-socket for strparser to process. This should be called from a data_ready
-callback that is set on the socket.
-
-strp_stop is called to completely stop stream parser operations. This
-is called internally when the stream parser encounters an error, and
-it is called from the upper layer when unattaching a TCP socket.
-
-strp_done is called to unattach the stream parser from the TCP socket.
-This must be called after the stream processor has be stopped.
-
-strp_check_rcv is called to check for new messages on the socket. This

Statistics
-----------
+==========
-Various counters are kept for each stream parser for a TCP socket.
-These are in the strp_stats structure. strp_aggr_stats is a convenience
-structure for accumulating statistics for multiple stream parser
-instances. save_strp_stats and aggregate_strp_stats are helper functions

Message assembly limits
------------------------
+=======================
The stream parser provide mechanisms to limit the resources consumed by
message assembly.
-A timer is set when assembly starts for a new message. The message
-timeout is taken from rcvtime for the associated TCP socket. If the
-timer fires before assembly completes the stream parser is aborted
-and the ETIMEDOUT error is set on the TCP socket.

+argument in strp_process. If the timer fires before assembly completes
+the stream parser is aborted and the ETIMEDOUT error is set on the TCP
+socket if in receive callback mode.
-Message length is limited to the receive buffer size of the associated
-TCP socket. If the length returned by parse_msg is greater than
-the socket buffer size then the stream parser is aborted with
-EMSGSIZE error set on the TCP socket. Note that this makes the
-maximum size of receive skbuffs for a socket with a stream parser

+/* Devmaps primary use is as a backend map for XDP BPF helper call
+ * bpf_redirect_map(). Because XDP is mostly concerned with performance we
+ * spent some effort to ensure the datapath with redirect maps does not use
+ * any locking. This is a quick note on the details.
+ *
+ * We have three possible paths to get into the devmap control plane bpf
+ * syscalls, bpf programs, and driver side xmit/flush operations. A bpf syscall
+ * will invoke an update, delete, or lookup operation. To ensure updates and
+ * deletes appear atomic from the datapath side xchg() is used to modify the
+ * netdev_map array. Then because the datapath does a lookup into the netdev_map
+ * array (read-only) from an RCU critical section we use call_rcu() to wait for
+ * an rcu grace period before free'ing the old data structures. This ensures the
+ * datapath always has a valid copy. However, the datapath does a "flush"
+ * operation that pushes any pending packets in the driver outside the RCU
+ * critical section. Each bpf_dtab_netdev tracks these pending operations using
+ * an atomic per-cpu bitmap. The bpf_dtab_netdev object will not be destroyed
+ * until all bits are cleared indicating outstanding flush operations have
+ * completed.
+ *
+ * BPF syscalls may race with BPF program calls on any of the update, delete
+ * or lookup operations. As noted above the xchg() operation also keep the
+ * netdev_map consistent in this case. From the devmap side BPF programs
+ * calling into these operations are the same as multiple user space threads
+ * making system calls.
+ *
+ * Finally, any of the above may race with a netdev_unregister notifier. The
+ * unregister notifier must search for net devices in the map structure that
+ * contain a reference to the net device and remove them. This is a two step
+ * process (a) dereference the bpf_dtab_netdev object in netdev_map and (b)
+ * check to see if the ifindex is the same as the net_device being removed.
+ * When removing the dev a cmpxchg() is used to ensure the correct dev is
+ * removed, in the case of a concurrent update or delete operation it is
+ * possible that the initially referenced dev is no longer in the map. As the
+ * notifier hook walks the map we know that new dev references can not be
+ * added by the user because core infrastructure ensures dev_get_by_index()
+ * calls will fail at this point.

-#
-# Usage:
-# - After configured vSwitch and vNIC with SRIOV, start Linux virtual
-# machine (VM)
-# - Run this scripts on the VM. It will create configuration files in
-# distro specific directory.
-# - Reboot the VM, so that the bonding config are enabled.
-#
-# The config files are DHCP by default. You may edit them if you need to change
