From 1dc329180fe22ff8651e0ef550ba17ca1cc7bf22 Mon Sep 17 00:00:00 2001
From: Joe Perches <joe@perches.com>
Date: Fri, 11 Jul 2008 15:17:08 -0700
Subject: e1000: Use hw, er32, and ew32

Use struct e1000_hw *hw = adapter->hw; where necessary
Change macros E1000_READ_REG and E1000_WRITE_REG to er32 and ew32
