From 67e7377661db4e341ed5e9a0358d11a55e532aa8 Mon Sep 17 00:00:00 2001 From: Dotan Barak Date: Wed, 1 Mar 2006 14:28:12 -0800 Subject: [PATCH] IB/mthca: Check alternate P_Key index when setting alternate path Check that the alternate P_Key index is in range when setting the alternate path for a QP. Also make a cosmetic touch up to the debug message printed when the main P_Key index is out of range.
