Update of /cvsroot/src/sys/netinet
In directory netbsd1:/var/slash-tmp/cvs-serv2766

Modified Files:
        ip.h ip_input.c 
Log Message:
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.
