Subject: [PATCH for-next] RDMA/core: fix ENODEV error for iwarp test over vlan
Date: Thu, 26 Sep 2024 11:37:08 +0530 [thread overview]
Message-ID: <20240926060708.82018-1-anumula@chelsio.com> (raw)
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.
