From e5f0508d43b45d138d426afcaa1e4cce7658cff4 Mon Sep 17 00:00:00 2001 From: Devesh Sharma Date: Mon, 24 Nov 2014 10:03:39 +0530 Subject: [PATCH] RDMA/ocrdma: Always resolve destination mac from GRH for UD QPs For user applications that use UD QPs, always resolve destination MAC from the GRH. This is to avoid failure due to any garbage value in the attr->dmac.
