commit fix in pr 2772 -- the IP input code was assuming that the
...
reserved (must be zero) flag must necessarily be zero. We now define
an IP_RF (by analogy to IP_DF and IP_MF) and mask it out when necessary.

through IP header overlays, add a "queue element" structure to do
the threading, and point it at the ip headers.
