From 7c27f358209a8ce7c57b584346d7b611e823f1b1 Mon Sep 17 00:00:00 2001 From: Roland Dreier Date: Mon, 14 Jul 2008 23:48:46 -0700 Subject: [PATCH] IB/mlx4: Remove extra code for RESET->ERR QP state transition Commit 65adfa91 ("IB/mlx4: Fix RESET to RESET and RESET to ERROR transitions") added some extra code to handle a QP state transition from RESET to ERROR. However, the latest 1.2.1 version of the IB spec has clarified that this transition is actually not allowed, so we can remove this extra code again.
