net: Use VRF device index for lookups on TX
As with ingress use the index of VRF master device for route lookups on egress. However, the oif should only be used to direct the lookups to a specific table. Routes in the table are not based on the VRF device but rather interfaces that are part of the VRF so do not consider the oif for lookups within the table. The FLOWI_FLAG_VRFSRC is used to control this latter part. Signed-off-by: Shrijeet Mukherjee <shm@cumulusnetworks.com> Signed-off-by: David Ahern <dsa@cumulusnetworks.com> Signed-off-by: David S.
