MFCing rev 1.96 of netinet/in.c for Zeroconf

[Bruce M Simpson]

The change itself is very simple;
    
http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/netinet/in.c.diff?r1=1.95&r2=1.96

This change is necessary before IPv4 address scope and source selection 
policy may be implemented.

Does anyone see any potential problems with this? It is possible that 
there are people out there forwarding between LANs with 169.254.0.0/16 
subnetted on different interfaces, though this is not RFC compliant 
behaviour, so I'd like to hear about that before I merge it.

Regards,
BMS
