From 313674afa8fdced2fe79f50f38e1c387b63d8790 Mon Sep 17 00:00:00 2001 From: Matthew Wilcox 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. Signed-off-by: Matthew Wilcox Signed-off-by: David S.
