From d44335572f76020ef473d7977d9fd424e6fc0021 Mon Sep 17 00:00:00 2001 From: Maor Gottlieb Date: Thu, 18 Jun 2020 14:25:07 +0300 Subject: RDMA/mlx5: Fix remote gid value in query QP Remote gid is not copied to the right address. Fix it by using rdma_ah_set_dgid_raw to copy the remote gid value from the QP context on query QP.
