Revamped dequeuing of TXd frames.
...
Now almost works (queues don't stay full of junk), although
mdp ping still gets a duplicate reply for 2-hop pings.

Fixed handling of duplicate broadcasts (they get dropped sooner).
...
There does seem to be something odd about the broadcast processing
still, as the BPIs change after resolving addresses.
Maybe when we send a broadcast out via multiple interfaces it
gets marked duplicate after sending to the first interface?
