"ethtool -S oob_net0" does not report interrupt counts

[David Thompson]

SRU Justification:

[Impact]
* The command "ethtool -S oob_net0" displays a set of statistics
  related to mlxbf_gige driver. This set of statistics does not
  include the driver's interrupt counts.

[Fix]
* The fix is to extend the statistics list supported by "ethtool -S"
  so that it includes MAC, receive packet, and LLU/PLU interrupt counts.

[Test Case]
* The command "ethtool -S oob_net0" should be executed before and
  after this fix to verify that three new fields are displayed:
        mac_intr_count
        rx_intr_count
        llu_plu_intr_count

[Regression Potential]
* There is low risk of this fix causing any problems.

[Other]
* n/a

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is awaiting verification that the linux-bluefield/5.4.0-1020.23 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

Hi David, may you please verify this bug is resolved in the kernel sitting in proposed? You can find instructions for how to complete that in comment #1. Thank you!
