Actually, there's something else than changed. The ng_fec module tries
to set ifp->if_output to ng_fec_output() so that it can do some output
processing on frames, however, later it would call ether_ifattach(),
which would set ifp->if_output to ether_output(), which wouldn't work.
I just commited a fix for this. (I verified that I can successfully
send packets via fec0.)
I also modified the input handling so that it no longer uses the
ng_ether_input_p hook. Now that FreeBSD 5.x has an ifp->if_input
vector, it's not necessary to abuse this hook anymore. This avoids
a collision with the ng_ether module, which is what was supposed to
be using this hook in the first place.
Let me know how this works.
