From 0d1ae7f46f1b51623bed2904576d15f6ecd5dc10 Mon Sep 17 00:00:00 2001 From: Alexander Duyck Date: Fri, 26 Aug 2011 07:46:34 +0000 Subject: [PATCH] igb: avoid unnecessarily creating a local copy of the q_vector This is mostly a drop of unnecessary pointer defines for q_vector when we don't have issues with line width and don't have multiple references to the pointer.
