freebsd/usr.sbin/mrouted/defs.h
Garrett Wollman 2897e6fd5f This is mrouted version 3.5, with the route-change notification hook from
mrouted-3.5n.  This is being splatted onto the head rather than properly
imported thanks to the ``delete trailing whitespace'' screw.  This code is
now actively working in an operational environment (the DARTNET) so I
have some confidence that the basic functionality actually works.
