fc9e668b4b o) Check that no overrun or CRC errors were encountered in receiving a 
packet.  Linux, OpenBSD and our iwn(4) all do this.  It also results in
   a huge performance improvement (and the rejection of a fair number of
   apparently-bad packets on receive) on my hardware.
o) Like the wpi(4) driver in OpenBSD, and like our iwn(4), also drop runt
   packets.
o) Don't bother doing IFQ_POLL and then IFQ_DRV_DEQUEUE, just do
   IFQ_DRV_DEQUEUE outright.  This is more similar to how OpenBSD and our
   iwn(4) work.
