Title:
  mlxbf_gige: disable RX_DMA during NAPI poll

Status in linux-bluefield package in Ubuntu:
  Invalid
Status in linux-bluefield source package in Jammy:
  Fix Committed

Bug description:
  SRU Justification:

  [Impact]

  A regression has been introduced in the latest 22.04 kernel by including
  the following two commits:
     revert "UBUNTU: SAUCE: Fix OOB handling RX packets in heavy traffic"
     addition of upstream "mlxbf_gige: fix receive packet race condition"
  The regression will manifest as connectivity problems on "oob_net0" interface

  [Fix]

  Modify the GIGE driver to include the RX_DMA disable logic in its NAPI poll 
routine
  This logic was part of "UBUNTU: SAUCE: Fix OOB handling RX packets in heavy 
traffic"
  but not part of upstream "mlxbf_gige: fix receive packet race condition"

  [Test Case]

  Boot BF3 platform and ensure oob_net0 interface is up and has IP address
  Bring up many IP interfaces, including oob_net0, and make sure OOB interface
  is continually accessible (e.g. via ping)

  [Regression Potential]

  Low risk change, adding back in prior logic.
