--- Comment #16 from Franco Fichtner <franco@opnsense.org> ---
I'm not so sure.  All branches received a modified patch that came up
inconclusive in testing, overshadowed by the iflib conversion and multiple
build and subsystem failures due to it.  We circled around a minimal patch
(note the attached patch reverts to the full Intel driver change), but the
weirdness that is "adapter->ims" for just this one chipset code path still
makes no sense in the grand scheme of things.

I asked for a full revert to the working Intel state via e-mail, but that
didn't happen.

I don't think this is sensible for the simple reason that this was introduc=
ed
in stable/10, went into 10.3 unnoticed, breaking *a lot* of embedded hardwa=
re
with regard to e.g. CARP, then went into 11.0.  It took a long time to iden=
tify
the commit that was responsible and unwind it (it was a batch MFC after all=
).

Settling for anything other than what is attached to this ticket is risky,
especially if there is nobody who can test and verify this in over one and a
half years.


Cheers,
Franco
