Hi Dave,
This series from Amir and Or deals with two enhancements for the mlx5 TC
offloads.
The 1st two patches add bulk reading of flow counters. Few bulk counter queries
are
used instead of issuing thousands firmware commands per second to get
statistics of all
flows set to HW.
The next patches add TC based SRIOV offloading to mlx5, as a follow up for the
e-switch
offloads mode and the VF representors. When the e-switch is set to the (new)
"offloads"
mode, we can now offload TC/flower drop and forward rules, the forward action
we offload
is TC mirred/redirect.
The above is done by the VF representor netdevices exporting the setup_tc ndo
where from
there we're re-using and enhancing the existing mlx5 TC offloads sub-module
which now
works for both the NIC and the SRIOV cases.
The series is applied on top b38a75d2d324 ('mlxsw: core: Trace EMAD messages')
and it has no merge issues with the on-going net submission ('mlx5 tx timeout
watchdog fixes')
V2:
- Fixed compilation warning.
Thanks,
Saeed.
