Merge branch 'net-atlantic-QoS-implementation'
Igor Russkikh says:
====================
net: atlantic: QoS implementation
This patch series adds support for mqprio rate limiters and multi-TC:
* max_rate is supported on both A1 and A2;
* min_rate is supported on A2 only;
This is a joint work of Mark and Dmitry.
To implement this feature, a couple of rearrangements and code
improvements were done, in areas of TC/ring management, allocation
control, etc.
One of the problems we faced is conflicting ptp functionality, which
consumes a whole traffic class due to hardware limitations.
Patches below have a more detailed description on how PTP and multi-TC
co-exist right now.
v2:
* accommodated review comments (-Wmissing-prototypes and
-Wunused-but-set-variable findings);
* added user notification in case of conflicting multi-TC<->PTP
configuration;
* added automatic PTP disabling, if a conflicting configuration is
detected;
* removed module param, which was used for PTP disabling in v1;
v1: https://patchwork.ozlabs.org/cover/1294380/
