mlxbf_gige: need to add BlueField-3 support

[David Thompson]

SRU Justification:

[Impact]

The GIGE driver ("mlxbf_gige") in the Jammy repo does not yet
support the BlueField-3 SoC. The "mlxbf_gige" driver which
supports BlueField-2 SoC currently will be extended to include
the BlueField-3 support.

[Fix]
The BlueField-3 support will be provided in the form of a set
of 4 patches, to be sent in as a pull request.

[Test Case]
BlueField-2: Boot platform and bring up "oob_net0" interface properly
             Test that network traffic works properly
BlueField-3: Tested in simulator platforms and early silicon

[Regression Potential]
Since this is initial support there is chance of regression
on BlueField-2 platforms, but it's been tested there.

[Other]
n/a

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is awaiting verification that the linux-bluefield/5.15.0-1010.12 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' to 'verification-done-jammy'. If the problem still exists, change the tag 'verification-needed-jammy' to 'verification-failed-jammy'.

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!
