Bug description:
During system initialization there is a specific sequence that must be
followed to enable the use of hardware offload and VF-LAG.
Intermittently one may see that VF-LAG initialization fails:
[Thu Jul 21 10:54:58 2022] mlx5_core 0000:08:00.0: lag map port 1:1 port 2:2
shared_fdb:1
[Thu Jul 21 10:54:58 2022] mlx5_core 0000:08:00.0: mlx5_cmd_check:782:(pid
9): CREATE_LAG(0x840) op_mod(0x0) failed, status bad parameter(0x3), syndrome
(0x7d49cb)
[Thu Jul 21 10:54:58 2022] mlx5_core 0000:08:00.0: mlx5_create_lag:248:(pid
9): Failed to create LAG (-22)
[Thu Jul 21 10:54:58 2022] mlx5_core 0000:08:00.0: mlx5_activate_lag:288:(pid
9): Failed to activate VF LAG
Make sure all VFs are unbound prior to VF LAG
activation or deactivation
This is caused by rebinding the driver prior to the VF lag being
ready.
A sysfs knob has recently been added to the driver [0] and we should
monitor it before attempting to rebind the driver:
$ cat /sys/kernel/debug/mlx5/0000\:08\:00.0/lag/state
The kernel feature is available in the upcoming Kinetic 5.19 kernel
and we should probably backport it to the Jammy 5.15 kernel.
