Investigate whether we can actually free these pages? If so, free and ensure that we're not leaking memory everywhere

page_stolen means that we have token this page off and allocate another page to map instead, this stolen page we can use to "handle_rxb" function, after using it, we should free.

Definitely free, but #4 needs to happen here too.. how do we tag the mbufs? Maybe within the metadata fields?

How about using mbuf_tag_allocate? add a global tag id to mbuf which is allocate from allocatePacket.
