From 80f12eccce775dc6bb93dba9b52529740f929237 Mon Sep 17 00:00:00 2001 From: Yuval Mintz Date: Wed, 6 Jun 2012 17:13:06 +0000 Subject: Added kernel support in EEE Ethtool commands This patch extends the kernel's ethtool interface by adding support for 2 new EEE commands - get_eee and set_eee. Thanks goes to Giuseppe Cavallaro for his original patch adding this support. Signed-off-by: Yuval Mintz Signed-off-by: Eilon Greenstein Reviewed-by: Ben Hutchings Signed-off-by: David S.
