Add a vendor patch:

= A bugfix for FreeBSD users (Quagga bug #326):
        * zebra_rib.[ch]: (rib_lookup_and_pushup) New function, which makes sure,
          that if_set_prefix() has nothing in its way of assigning an address.
        * ioctl.c: (if_set_prefix) Use rib_lookup_and_pushup() to resolve
          bug #326.

Approved by:	maintainer (implicitly)
