This is a note to let you know that I've just added the patch titled RDMA/irdma: Initialize net_type before checking it to the 6.1-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-irdma-initialize-net_type-before-checking-it.patch and it can be found in the queue-6.1 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 99f1412129266337159114e4770c287f189bca4e Author: Mustafa Ismail <mustafa.ismail@xxxxxxxxx> Date: Mon Nov 21 18:44:10 2022 -0600 RDMA/irdma: Initialize net_type before checking it [ Upstream commit 9907526d25c4ad8a6e3006487a544140776ba005 ] The av->net_type is not initialized before it is checked in irdma_modify_qp_roce. This leads to an incorrect update to the ARP cache and QP context. RoCEv2 connections might fail as result. Set the net_type using rdma_gid_attr_network_type.
