[SRU][F:linux-bluefield][PATCH v2 0/1] UBUNTU: SAUCE: mlxbf-gige: Enable the OOB port in mlxbf_gige_open

[Asmaa Mnebhi]

BugLink: https://bugs.launchpad.net/bugs/2035128

SRU Justification:

[Impact]

At the moment, the OOB port is enabled in the mlxbf_gige_probe function. If the mlxbf_gige_open is not executed, this could cause pause frames to increase in the case where there is high backgroud traffic. This results in clogging the BMC port as well.

[Fix]

* Move enabling the OOB port to mlxbf_gige_open.

[Test Case]

* Main test for this bug: Check that the BMC is always pingable while pushing a BFB

Other tests:
* Check if the gige driver is loaded
* Check that the oob_net0 interface is up and operational
* Do the reboot test and powercycle test and check the oob_net0 interface again
* Push BFB multiple times and make sure the OOB is up and running

[Regression Potential]

Since are moving code that hasn't moved since BF2, it is important to make sure that there is no regression.
Make sure that the OOB interface is always up and pingable after the reboot test, the powercycle test and after pushing a BFB.
