This is a note to let you know that I've just added the patch titled RDMA/core: Fix ENODEV error for iWARP test over vlan to the 6.11-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: rdma-core-fix-enodev-error-for-iwarp-test-over-vlan.patch and it can be found in the queue-6.11 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit acd3754bcca1ae970db4f1cbcba050951beaa041 Author: Anumula Murali Mohan Reddy <anumula@xxxxxxxxxxx> Date: Tue Oct 8 17:13:34 2024 +0530 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.
