Public bug reported:
SRU Justification:
[Impact]
During the reboot and power cycle testing, QA found an intermittent issue
where "oob_net0" interface would experience RX MAC errors and fail to get
a DHCP-assigned IP. There is a small window where packets can be received
before the RX path is fully initialized, sometimes resulting in RX errors
or RX ring full condition.
[Fix]
* Disable MAC RX filters in driver's probe() and only enable these RX
filters in driver's open() when all initialization is completed.
[Test Case]
* On BlueField-2 and BlueField-3, do reboot and power cycle testing
* Check that "oob_net0" interface is up, IP is assigned, and there are no RX
errors.
[Regression Potential]
* no known regression.
** Affects: linux-bluefield (Ubuntu)
