It's having IGB_LEGACY_TX turned on that makes it panic.  That also makes it
use one queue.  I'm guessing igb(4) may also work with ALTQ with IGB_LEGACY_TX
disabled, and hw.igb.num_queues=1 set, but that's not something I need on this
particular box.

I've got em(4) on the external interface, and igb(4) on the internal
interfaces.  I'm only using ALTQ for the external interface.

I could reconfigure it and try that out, but I'd rather not take the box down
if I can help it. :)
