I assumed you checked to see if there's a firmware update for your
card and if so, applied it?

Here is what I would do if I was in your shoes.  First I would file a PR
and make it as complete as possible.  Second I would explore using different
model network cards if you have the slots for them.  Life is too short to
wait around for the developers to fix a driver bug.  As much as I am
pro FreeBSD even I've been bit by network adapter driver bugs, and been
forced to disable or abandon NICs that worked nicely under Windows
in a system.  And, having a stable network adapter is in my opinion
pretty much a requirement for a FreeBSD system.
