I'm wrong, it's more than just the header.  I went through this in
great detail quite a while ago.  Look at ppp and tun for hints,
you probably have to change the bpf_attach() call too.  And I'd
move the bpf_mtap() in the output routine way up to the top,
since right now it completely misses the LINK0 case, and even
if it doesn't the output routine has already zeroed out the length
field in each mbuf in the chain.

Fun fun.
