[PATCH net-next V2 00/10] Mellanox 100G mlx5 Bulk flow statistics and SRIOV TC offloads

[Saeed Mahameed]

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.

  net/mlx5: Store counters in rbtree instead of list
  net/mlx5: Introduce bulk reading of flow counters

Or Gerlitz (8):

  net/mlx5: E-Switch, Use two priorities for SRIOV offloads mode
  net/mlx5: E-Switch, Add API to configure rules for the offloaded mode
  net/mlx5e: Adjustments in the TC offload code towards reuse for SRIOV
  net/switchdev: Export the same parent ID service function
  net/mlx5e: Add TC drop and mirred/redirect action parsing for SRIOV
offloads
  net/mlx5e: Add TC HW support for FDB (SRIOV e-switch) offloads
  net/mlx5e: Add TC offload support for the VF representors netdevice
