From 6b0c54060ecb678473d442bba01fcb2b3079f594 Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Tue, 25 Nov 2014 21:16:36 -0800 Subject: [PATCH] net: bcmgenet: support restarting auto-negotiation Hook a nway_reset ethtool callback to allow restarting the auto-negotiation process when asked to. We defer to the PHY library call to do the heavy lifting. Signed-off-by: Florian Fainelli Signed-off-by: David S.
