New Revision: 226710
URL: http://svn.freebsd.org/changeset/base/226710
Log:
The host-id/interface-id can have a specific value and is properly
masked out when adding a prefix route through the "route" command.
However, when deleting the route, simply changing the command keyword
from "add" to "delete" does not work. The failoure is observed in
both IPv4 and IPv6 route insertion. The patch makes the route command
behavior consistent between the "add" and the "delete" operation.
