The MPLS code now needs it.

Fixes: 397fc9e5 ("mpls: route get support")
Signed-off-by: NDavid S. Miller <davem@davemloft.net>

This patch adds RTM_GETROUTE doit handler for mpls routes.

Input:
RTA_DST - input label
RTA_NEWDST - labels in packet for multipath selection

By default the getroute handler returns matched
nexthop label, via and oif

With RTM_F_FIB_MATCH flag, full matched route is
returned.

example (with patched iproute2):
$ip -f mpls route show
101
        nexthop as to 102/103 via inet 172.16.2.2 dev virt1-2
