If traffic is over vlan, cma_validate_port() fails to match vlan net_device ifindex with bound_if_index and results in ENODEV error. It is because rdma_copy_src_l2_addr() always assigns bound_if_index with real net_device ifindex. This patch fixes the issue by assigning bound_if_index with vlan net_device index if traffic is over vlan.
