====================
mlx5-updates-2022-05-09

1) Gavin Li, adds exit route from waiting for FW init on device boot and
   increases FW init timeout on health recovery flow

2) Support 4 ports HCAs LAG mode

Mark Bloch Says:
================

This series adds to mlx5 drivers support for 4 ports HCAs.
Starting with ConnectX-7 HCAs with 4 ports are possible.

As most driver parts aren't affected by such configuration most driver
code is unchanged.

Specially the only affected areas are:
- Lag
- Devcom
- Merged E-Switch
- Single FDB E-Switch

Lag was chosen to be converted first. Creating hardware LAG when all 4
ports are added to the same bond device.

Devom, merge E-Switch and single FDB E-Switch, are marked as supporting
only 2 ports HCAs and future patches will add support for 4 ports HCAs.

In order to activate the hardware lag a user can execute the:

ip link add bond0 type bond
ip link set bond0 type bond miimon 100 mode 2
ip link set eth2 master bond0
ip link set eth3 master bond0
ip link set eth4 master bond0
ip link set eth5 master bond0

Where eth2, eth3, eth4 and eth5 are the PFs of the same HCA.
