[SRU][F:linux-bluefield][PATCH 09/32] mlx5: become aware of when running as a bonding slave

[Daniel Jurgens]

From: Jarod Wilson <jarod at redhat.com>

BugLink: https://bugs.launchpad.net/bugs/1926994

I've been unable to get my hands on suitable supported hardware to date,
but I believe this ought to be all that is needed to enable the mlx5
driver to also work with bonding active-backup crypto offload passthru.
