Ok, this patch:

	http://people.freebsd.org/~pjd/patches/no_old_style_nets.patch

removes ia_netbroadcast, ia_net, ia_netmask field from structure
in_ifaddr and removes sysctl net.inet.ip.subnets_are_local as suggested
in commit log of revision 1.24 of file netinet/in.c:

Set subnetsarelocal to false.  In a classless world, the other case
is almost never useful.  (This is only a quick hack; someone should
go back and delete the entire subnetsarelocal==1 code path.)

Tests and comments are welcome.
