Subject: [PATCH v2 net-next 00/12] 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/

Dmitry Bezrukov (4):
  net: atlantic: changes for multi-TC support
  net: atlantic: move PTP TC initialization to a separate function
