From 313674afa8fdced2fe79f50f38e1c387b63d8790 Mon Sep 17 00:00:00 2001
From: Matthew Wilcox <matthew@wil.cx>
Date: Tue, 31 Jul 2007 14:00:29 -0700
Subject: [PATCH] [NET]: ethtool_perm_addr only has one implementation

All drivers implement ethtool get_perm_addr the same way -- by calling
the generic function.  So we can inline the generic function into the
caller and avoid going through the drivers.
