11 any other computer at all.

14 you want to use under Linux. If you are going to run SLIP or PPP over

361 This is a driver for the General Instrument (also known as
362 NextLevel) SURFboard 1000 internal
363 cable modem. This is an ISA card which is used by a number of cable
364 TV companies to provide cable modem access. It's a one-way
365 downstream-only cable modem, meaning that your upstream net link is
366 provided by your regular phone modem.
367
368 At present this driver only compiles as a module, so say M here if
369 you have this card. The module will be called sb1000. Then read
370 <file:Documentation/networking/README.sb1000> for information on how
371 to use this module, as it needs special ppp scripts for establishing
372 a connection. Further documentation and the necessary scripts can be
373 found at:

376 <http://home.adelphia.net/~siglercm/sb1000.html>
377 <http://linuxpower.cx/~cable/>
378
379 If you don't have this card, of course say N.

Ian Campbellf942dc22011-03-15 00:06:18 +0000407 This driver provides support for Xen paravirtual network
408 devices exported by a Xen network driver domain (often
409 domain 0).
410
411 The corresponding Linux backend driver is enabled by the
412 CONFIG_XEN_NETDEV_BACKEND option.
413
414 If you are compiling a kernel for use as Xen guest, you
415 should say Y here. To compile this driver as a module, chose
416 M here: the module will be called xen-netfront.

420 depends on XEN_BACKEND
421 help
422 This driver allows the kernel to act as a Xen network driver
423 domain which exports paravirtual network devices to other
424 Xen domains. These devices can be accessed by any operating
425 system that implements a compatible front end.
426
427 The corresponding Linux frontend driver is enabled by the
428 CONFIG_XEN_NETDEV_FRONTEND configuration option.
429
430 The backend driver presents a standard network device
431 endpoint for each paravirtual network device to the driver
432 domain network stack. These can then be bridged or routed
433 etc in order to provide full network connectivity.
434
435 If you are compiling a kernel to run in a Xen network driver
436 domain (often this is domain 0) you should say Y here. To
437 compile this driver as a module, chose M here: the module
438 will be called xen-netback.
