  For the benefit of new NIC cards that can offload a lot of the inbound
hooks, it would be nice if there was a way to mark an mbuf as having been
already processed by the inbound filters. It may be that this should be
integer that gets incremented so that some can run feed packets back into the 
bottom of the stack and have only the appropriate level of filtering
apply. (This isn't just for the IPsec case, for which we already have policy code)
