* XXX these routines are called from the upper part of the kernel.

* They could also be moved to ip_mroute.c, since all the RSVP
* handling is done there already.
* XXXRW: Multicast routing code in ip_mroute.c is generally MPSAFE, but the
* ip_rsvp and ip_rsvp_on variables need to be interlocked with rsvp_on
* locking. This code remains in ip_input.c as ip_mroute.c is optionally
