Well I don't care exactly how we do it but we need to figure out a way of storing such metadata along with packets. and it needs to be queueable along with the packets.. (sounds like an mbuf to me but if you have a better idea.....) (and anyhow Garrett got rid of the 'static' uses of mbufs, not 'travelling' 'per packet' uses..)
