From 3bc12e75b23c0499cc2c0873a5f77494be173761 Mon Sep 17 00:00:00 2001 From: Roland Dreier Date: Sun, 30 Oct 2005 13:20:09 -0800 Subject: [PATCH] [IPoIB] cleanups: fix comment, remove useless variables Minor cleanups: fix a misleading comment, and get rid of attr_mask variables that are only used to hold constants (just use the constants directly).
