[PATCH net-next 12/15] net/mlx5e: Add direct TIRs to devlink rx reporter diagnose

[Tariq Toukan <tariqt@nvidia.com>]

From: Amir Tzin <amirtz@nvidia.com>

Add "RX resources" tag to the output of rx reporter diagnose callback.
Underneath add tag for direct TIRs, for each TIR expose its tirn and
the corresponding rqtn.

$ sudo devlink health diagnose auxiliary/mlx5_core.eth.0/65535 reporter rx
 ....
 rx resources:
   Direct TIRs:
       ix: 0 tirn: 20 rqtn: 1
       ix: 1 tirn: 21 rqtn: 2
       ix: 2 tirn: 22 rqtn: 3
       ix: 3 tirn: 23 rqtn: 4
       ix: 4 tirn: 24 rqtn: 5
       ix: 5 tirn: 25 rqtn: 6
       ix: 6 tirn: 26 rqtn: 7
       ix: 7 tirn: 27 rqtn: 8
       ix: 8 tirn: 28 rqtn: 9
       ix: 9 tirn: 29 rqtn: 10
       ix: 10 tirn: 30 rqtn: 11
       ix: 11 tirn: 31 rqtn: 12
       ix: 12 tirn: 32 rqtn: 13
