Add vrf keyword to 'ip route' commands. Allows:
1. Users can list routes by VRF name:
$ ip route show vrf NAME
VRF tables have all routes including local and broadcast routes.
The VRF keyword filters LOCAL and BROADCAST routes; to see all
routes the table option can be used. Or to see local routes only
for a VRF:
$ ip route show vrf NAME type local
Contrast with current syntax:
$ ip route show table ID
where the user needs to find the vrf to table ID or maintain a
text file in /etc/iproute2/rt_tables.d.
2. Add or delete a route for a VRF:
$ ip route {add|delete} vrf NAME <route spec>
Similarly for this command, users currently need to use table
option and know the table id or maintain a mapping.
3. Do a route lookup for a VRF:
$ ip route get vrf NAME ADDRESS
Contrast with current syntax:
$ ip route get oif DEV ADDRESS
(specifying table id for route get does not work kernel side).
