[ Upstream commit a53c102872ad6e34e1518e25899dc9498c27f8b1 ]
When a qdisc is attached to the VRF device, the packet goes down the ndo
xmit function which is setup to send the packet back to the VRF driver
which does a lookup to send the packet out. The lookup in the VRF driver
is not considering xfrm policies. Change it to use ip6_dst_lookup_flow
rather than ip6_route_output.
Fixes: 35402e313663 ("net: Add IPv6 support to VRF device")
