Title:
mlxbf_gige: Ethtool speed does not update based on link status
Status in linux-bluefield package in Ubuntu:
New
Status in linux-bluefield source package in Jammy:
New
Status in linux-bluefield source package in Noble:
New
Bug description:
SRU Justification:
[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.
