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
