em(4) interface hangs under 8.0-RELEASE

[Nick Rogers]

ALTQ + RELENG_8 + em(4) will not work at the moment. It does not matter what
your PF ruleset looks like or how much traffic you are pushing. The packets
that transit the em interface simply never make it to the ALTQ queues (not
even the interface's root queue). Thus any kind of bandwidth rate limiting
or whatever you are doing will not work.

This was fixed by the following commit. I think its supposed to MFC soon?
