iproute: extend route get for mpls routesflag-names
This patch extends route get to support mpls specific
route attributes like RTA_NEWDST.
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 fibmatch keyword (RTM_F_FIB_MATCH flag), full matched
route is returned.
example:
$ip -f mpls route show
101
nexthop as to 102/103 via inet 172.16.2.2 dev virt1-2
nexthop as to 302/303 via inet 172.16.12.2 dev virt1-12
201
nexthop as to 202/203 via inet6 2001:db8:2::2 dev virt1-2
nexthop as to 402/403 via inet6 2001:db8:12::2 dev virt1-12
$ip -f mpls route get 103
RTNETLINK answers: Network is unreachable
$ip -f mpls route get 101
101 as to 102/103 via inet 172.16.2.2 dev virt1-2
$ip -f mpls route get as to 302/303 101
101 as to 302/303 via inet 172.16.12.2 dev virt1-12
$ip -f mpls route get fibmatch 103
RTNETLINK answers: Network is unreachable
$ip -f mpls route get fibmatch 101
101
nexthop as to 102/103 via inet 172.16.2.2 dev virt1-2
nexthop as to 302/303 via inet 172.16.12.2 dev virt1-12
