mlx5-updates-2021-08-16

Browse source 
The following patchset provides two separate mlx5 updates
 1) Ethtool RSS context and MQPRIO channel mode support:
   1.1) enable mlx5e netdev driver to allow creating Transport Interface RX
        (TIRs) objects on the fly to be used for ethtool RSS contexts and
        TX MQPRIO channel mode
   1.2) Introduce mlx5e_rss object to manage such TIRs.
   1.3) Ethtool support for RSS context
   1.4) Support MQPRIO channel mode
 
 2) Bridge offloads Lag support:
    to allow adding bond net devices to mlx5 bridge
   2.1) Address bridge port by (vport_num, esw_owner_vhca_id) pair
        since vport_num is only unique per eswitch and in lag mode we
        need to manage ports from both eswitches.
   2.2) Allow connectivity between representors of different eswitch
        instances that are attached to same bridge
   2.3) Bridge LAG, Require representors to be in shared FDB mode and
        introduce local and peer ports representors,
        match on paired eswitch metadata in peer FDB entries,
        And finally support addition/deletion and aging of peer flows.
