I added a handful of interface flags to 1.4T, and one of them was
BPFONLY; when set, packet reception short-circuits everything after
bpf. Not quite what you want, because it affects input only.
The most difficult part was finding (and fixing) everything that
treated interface flags as a 16-bit bitmask; I can't believe it would
be all that hard to add to -current.
