This is a patch to sys/net/if.c. What it does is patch the algorithm
for finding an IP address on an interface which most closely matches
a given IP address. The problem with it is when no address matches,
and you have to just pick one at random. Then the code ends up picking
the last IP address in the list. This patch changes things so it
picks up the first address instead.
Usually the first address is more useful as the later ones are aliases.
