Subject: net/mlx5e: Extend tx reporter diagnostics output
Patch-mainline: v5.4-rc1
Git-commit: 2d708887a4b1cb142c3179b3b1030dab047467b6
References: jsc#SLE-8464
Enhance tx reporter's diagnostics output to include: information common
to all SQs: SQ size, SQ stride size.
In addition add channel ix, tc, txq ix, cc and pc.
$ devlink health diagnose pci/0000:00:0b.0 reporter tx
Common config:
SQ:
stride size: 64 size: 1024
SQs:
channel ix: 0 tc: 0 txq ix: 0 sqn: 4307 HW state: 1 stopped: false cc: 0 pc: 0
channel ix: 1 tc: 0 txq ix: 1 sqn: 4312 HW state: 1 stopped: false cc: 0 pc: 0
channel ix: 2 tc: 0 txq ix: 2 sqn: 4317 HW state: 1 stopped: false cc: 0 pc: 0
channel ix: 3 tc: 0 txq ix: 3 sqn: 4322 HW state: 1 stopped: false cc: 0 pc: 0
$ devlink health diagnose pci/0000:00:0b.0 reporter tx -jp
