net: Lookup actual route when oif is VRF device
If the user specifies a VRF device in a get route query the custom route
pointing to the VRF device is returned:
$ ip route ls table vrf-red
unreachable default
broadcast 10.2.1.0 dev eth1 proto kernel scope link src 10.2.1.2
10.2.1.0/24 dev eth1 proto kernel scope link src 10.2.1.2
local 10.2.1.2 dev eth1 proto kernel scope host src 10.2.1.2
broadcast 10.2.1.255 dev eth1 proto kernel scope link src 10.2.1.2
$ ip route get oif vrf-red 10.2.1.40
10.2.1.40 dev vrf-red
cache
Add the flags to skip the custom route and go directly to the FIB. With
this patch the actual route is returned:
$ ip route get oif vrf-red 10.2.1.40
10.2.1.40 dev eth1 src 10.2.1.2
cache
