gary@palmer:~/cvswork/2.2/sys> grep pr_input */*.[ch]
netinet/ip_input.c:	(*inetsw[ip_protox[ip->ip_p]].pr_input)(m, hlen);
netinet/ip_mroute.c:              old_proto4_input = inetsw[ip_protox[ENCAP_PROTO]].pr_input;
netinet/ip_mroute.c:              inetsw[ip_protox[ENCAP_PROTO]].pr_input = X_ipip_input;
netinet/ip_mroute.c:              inetsw[ip_protox[ENCAP_PROTO]].pr_input = old_proto4_input;
sys/protosw.h: * the pr_input and pr_output hooks.  Pr_input passes data up (towards
sys/protosw.h:	void	(*pr_input) __P((struct mbuf *, int len));

Huh. Looks like it's just used in the TCP/IP stuff for passing to the
appropriate protocol handler. I think it's safe to assume then that
the `raw_input' could be replaced with a `0' with no damage. Garrett?
Any objections? Or should the entire `raw_*' section be ripped out of
localsw?
