RDMA/core: Fix ENODEV error for iWARP test over vlan
[ Upstream commit 5069d7e202f640a36cf213a432296c85113a52f7 ]
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.
