Considering if_enc.c from OpenBSD's HEAD (see URLs at the bottom), it
does not seem to be difficult to port to FreeBSD, but since I'm not a
kernel guru at all, there may be some issues I don't even suspect.o

I'm concious that making it FreeBSD's SMP compliant should require a
little amount of work, but it could be maked with the IFF_NEEDSGIANT
flag for a first step.  Are there any reason why we would not need nor
want this in FreeBSD ?
