This bug is awaiting verification that the linux-
bluefield/5.15.0-1064.66 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-jammy-linux-bluefield' to
'verification-done-jammy-linux-bluefield'. If the problem still exists,
change the tag 'verification-needed-jammy-linux-bluefield' to
'verification-failed-jammy-linux-bluefield'.


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:
  revert SAUCE patches for mlxbf-tmfifo driver

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

Bug description:
  [Description]
  The following SAUCE patches should be reverted and replaced with upstream 
commits:
  7789adb5fe90 UBUNTU: SAUCE: mlxbf-tmfifo: fix potential race
  3d8185022ec5 UBUNTU: SAUCE: platform/mellanox: mlxbf-tmfifo: Add BlueField-3 
support

  [Impact]
  Align with upstream commits.

  [Fix]
  Other two commits are depended on the commits and need reverted. The reverted 
commits are:
  fe4595c4d14e platform/mellanox: mlxbf-tmfifo: Drop Tx network packet when Tx 
TmFIFO is full
  7789adb5fe90 UBUNTU: SAUCE: mlxbf-tmfifo: fix potential race
  3d77627b0ada UBUNTU: SAUCE: platform/mellanox: Add ctrl message and MAC 
configuration
  3d8185022ec5 UBUNTU: SAUCE: platform/mellanox: mlxbf-tmfifo: Add BlueField-3 
support

  Upstream ones are using ACPI API and this one should be cherry-picked too.
  5db72fd  ACPI: utils: Add acpi_dev_uid_to_integer() helper to get _UID as 
integer

  [Test Case]
  1. Get the iperf data with current mlxbf_tmfifo module.
  2. Unload mlxbf_tmfifo and load the newly built module. Get the iperf data.
  3. Make sure it works and no performance degradation.
