I'm seeing a similar situation with an Intel 10G card. This past week Jordan Hubbard stated that it was an issue with the Intel drivers and there was no fix possible.

Seeing that this issue would be shared with FreeBSD I did some looking around and found that it indeed was a problem with FreeBSD.
A fix was checked into the FreeBSD kernel repository about three weeks ago that is supposed to fix the issue.

Is there any chance we get this into the FreeNAS code so those of us can run with the Intel cards? I'm willing to help out if there's anything useful I could do.
