This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
focal' to 'verification-done-focal'. If the problem still exists, change
the tag 'verification-needed-focal' to 'verification-failed-focal'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

Title:
  Sync up mlxbf-gige driver with upstreamed version

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

Bug description:
  SRU Justification:

  [Impact]

  The mlxbf-gige driver has just been upstreamed so linux-bluefield needs to be 
synced up with what we have upstreamed.
  IMPORTANT: during testing, make sure the latest UEFI (bootloader) is loaded 
on top of these changes, otherwise both the gpio driver and mlxbf-gige driver 
will fail to load.

  [Fix]

  * reverted 20 commits related to the mlxbf-gige driver and 1 commit related 
to gpio-mlxbf2 driver since there are dependencies between them.
  * Cherry-picked f92e1869d74e1acc6551256eb084a1c14a054e19 from net-next 
branch. The upstreamed version of the GPIO driver removed the dependency 
between the mlxbf-gige driver and gpio-mlxbf2 driver.
  * added code that was left out of the upstreamed version. and added code that 
got reverted in gpio-mlxbf2.c
  * updated the UEFI ACPI table to reflect the above changes (so the bootloader 
and the linux drivers need to be in sync)

  [Test Case]

  * oob_net0 coming up after several SW_RESET or reboot
  * oob_net0 coming up after several powercycles
  * oob_net0 coming up after pushing a new Ubuntu/CentOS/Yocto
  * rmmod/modprove mlxbf_gige several times
  * OOB PXE boot multiple times from UEFI menu
  * automate OOB PXE boot and do reboot
  * automate OOB PXE boot and do powercycle
  * Test that GPIO7 reset still works on BlueSphere like boards

  [Regression Potential]

  Any of the test cases above could be impacted due to these changes.
