Function in_pcbgroup_update

freebsd/netinet/in_pcbgroup.c:469–493

* Two update paths: one in which the 4-tuple on an inpcb has been updated * and therefore connection groups may need to change (or a wildcard entry * may needed to be installed), and another in which the 4-tuple has been * set as a result of a packet received, in which case we may be able to use * the hash on the mbuf to avoid doing a software hash calculation for RSS. * * In each case: firs

 * otherwise, calculate and update the pcbgroup for the inpcb.
