mlxbf-gige: Vitesse PHY stuck in a bad state during reboot test

[Asmaa Mnebhi]

SRU Justification:

[Impact]

During the QA reboot test, the BF3 Vitesse PHY gets stuck in a bad state, resulting in no ip provisioning. The only way to recover is to powercycle.
We found a software workaround to avoid getting in this state in the first place: disable the OOB port in the shutdown function.

[Fix]

* Prevent the PHY from entering this bad state by disabling the OOB port
  during shutdown.

[Test Case]

* do the reboot test (at least 2000 reboots): run 'reboot' from linux.
* Check that the oob_net0 interface is up and the ip is assigned.
* please note that if the the OOB doesn't get an ip, try reloading the driver (rmmod/modprobe). it that solves the issue, that would be a different bug. In the bug at stake, nothing recovers the OOB ip except power cycle.

[Regression Potential]

* Make sure the redfish DHCP is still working during the reboot test
* Make sure the OOB gets an ip

This SW WA didnt work so the HW team will have to review it.

Reopening this bug since we found a software workaround for it.

This bug is awaiting verification that the linux-bluefield/5.4.0-1086.93 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-linux-bluefield' to 'verification-done-focal-linux-bluefield'. If the problem still exists, change the tag 'verification-needed-focal-linux-bluefield' to 'verification-failed-focal-linux-bluefield'.

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.

Re-add verification-done-jammy-linux-bluefield tag (it was removed by ubuntu-kernel-bot after incorrect removal of kernel-spammed-jammy-linux-bluefield-v2 tag).
