Module Name:    src
Committed By:   roy

        src/sys/netinet: in.c in.h

Log Message:
inet: Add support for IPv4 /31 prefixes, as described in RFC 3021.

To run a /31 network, participating hosts MUST drop support
for directed broadcasts, and treat the first and last addresses
on subnet as unicast. The broadcast address for the prefix
should be the link local broadcast address, INADDR_BROADCAST.

Taken from FreeBSD, r226402.
Fixes PR kern/51388.
