- Make transmission of packets work again. This stopped working because
ether_ifattach() was forcing ifp->if_output to be ether_output() and
clobbering our attempt to override this vector with a pointer to
ng_fec_output(). Move the overriding of ifp->if_output to after
ether_ifattach().
- Abandon the use of the netgraph ng_ether_input_p hook for snagging
incoming frames, and instead override the ifp->if_input vector for
interfaces that have been aggregated into our bundle. (I would have
loved to have written things this way in the first place, but I
didn't want to have to be the one to implement the if_input hook
and change all the drivers.) This avoids collisions with the ng_ether
module, which uses the same hook. Each aggregated device now calls
ng_fec_input() directly, which then fakes up the rcvif pointer
before invoking ifp->if_input itself.
This module should actually work now.
