====================
mlx5-updates-2022-07-13

1) Support 802.1ad for bridge offloads

Vlad Buslov Says:
=================

Current mlx5 bridge VLAN offload implementation only supports 802.1Q VLAN
Ethernet protocol. That protocol type is assumed by default and
SWITCHDEV_ATTR_ID_BRIDGE_VLAN_PROTOCOL notification is ignored.

In order to support dynamically setting VLAN protocol handle
SWITCHDEV_ATTR_ID_BRIDGE_VLAN_PROTOCOL notification by flushing FDB and
re-creating VLAN modify header actions with a new protocol. Implement support
for 802.1ad protocol by saving the current VLAN protocol to per-bridge variable
and re-create the necessary flow groups according to its current value (either
use cvlan or svlan flow fields).
==================

2) debugfs to count ongoing FW commands

3) debugfs to query eswitch vport firmware diagnostic counters

4) Add missing meter configuration in flow action

5) Some misc cleanup
