Using 5.15.0-1062-bluefield, was able to see the "RUNNING" status and oob_net0
got an IP too.

Title:
mlxbf_gige: move BF2 autoneg logic out of open()
Status in linux-bluefield package in Ubuntu:
New
Status in linux-bluefield source package in Jammy:
Fix Committed
Bug description:
SRU Justification:
[Impact]
The mlxbf_gige driver open() method includes a segment of BF2-specific
code that waits for autoneg completion before proceeding. The open()
method should not pend waiting for this link up event.
[Fix]
The fix is to move BF2 autoneg logic out of open(), replacing it with
logic that runs asynchronous to open() via a workqueue function.
[Test Case]
Boot BF2 with mlxbf_gige driver containing fix
Verify autoneg completes, i.e. "RUNNING" status shown in "ifconfig oob_net0"
Verify IP address is assigned to oob_net0
[Regression Potential]
Low - workqueue logic is quite simple
