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 Signed-off-by: David Ahern <dsa@cumulusnetworks.com> Signed-off-by: David S.
