It's likely that the mbuf handling problem (in em_refresh_mbufs()) is
triggered by the processing you're doing with ipfw (or elsewhere for
that matter), so, yes, I think it's a bug fixed in the revision
discussed.

When you update and test, please let us know. Also, don't forget to
submit a follow-up to your PR.

Thanks!
