[SRU][J:linux-bluefield][PATCH v1 0/1] UBUNTU: SAUCE: mlxbf_gige: Ethtool speed does not update based on link status

[Chris Babroski]

BugLink: https://bugs.launchpad.net/bugs/2116284

[Impact]
The "Speed" and "Duplex" fields displayed by ethtool should report "Unknown" when the link is down, but instead they continue to show "1000Mb/s" and "Full".

[Fix]
* Set the speed and duplex values reported to ethtool to unknown when the link is down.

[Test Case]
* Verified ethtool reports correct speed and duplex values based on link status.
  1. ethtool oob_net0
  2. ifconfig oob_net0 down
  3. ifconfig oob_net0
* Verified basic OOB interface behavior by SSHing to BlueField via OOB.

[Regression Potential]
* The fix affects BlueField 2 and BlueField 3, but the change is relatively small and only affects the data that is used by ethtool.
