From 3b04ddde02cf1b6f14f2697da5c20eca5715017f Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Tue, 9 Oct 2007 01:40:57 -0700 Subject: [NET]: Move hardware header operations out of netdevice. Since hardware header operations are part of the protocol class not the device instance, make them into a separate object and save memory. Signed-off-by: Stephen Hemminger Signed-off-by: David S.
