Function ng_eiface_start

freebsd/netgraph/ng_eiface.c:289–302

* This routine is called to deliver a packet out the interface. * We simply queue the netgraph version to be called when netgraph locking * allows it to happen. * Until we know what the rest of the networking code is doing for * locking, we don't know how we will interact with it. * Take comfort from the fact that the ifnet struct is part of our * private info and can't go away while we are

 * somehow, but we can't and if we did would we solve anything?
