[Tim Gardner]

SRU Justification

[Impact]

SRIOV tests fail where sometimes 0 and other times only 6 VF devices are detected instead of 8.
This is using the 5.19 Edge kernel.
Example failure from LISA test run -
Sriov.verify_sriov_provision_with_max_nics_reboot: FAILED failed. AssertionError: [VF count inside VM is 6,actual sriov nic count is 8] Expected <6> to be equal to <8>, but was not.

Microsoft has requested the inclusion of [1], now in linux-next.

[Test Plan]

Microsoft tested

[Where things could go wrong]

VNICs could continue to go undetected.
