From 851d7b6b8a954b28f85e62a53cbba472907e21e4 Mon Sep 17 00:00:00 2001 From: Steve Wise Date: Tue, 12 Apr 2016 06:54:54 -0700 Subject: [PATCH] iw_cxgb4: initialize ibdev.iwcm->ifname for port mapping The IWCM uses ibdev.iwcm->ifname for registration with the iwarp port map daemon. But iw_cxgb4 did not initialize this field which causes intermittent registration failures based on the contents of the uninitialized memory.
