Subject: [PATCH 13/34] net: dsa: bcm_sf2: Ensure we re-negotiate EEE during after link change

From: Florian Fainelli <[email-masked]>
Date: Tue, 22 Nov 2016 11:40:58 -0800

[ Upstream commit 76da8706d90d8641eeb9b8e579942ed80b6c0880 ]

In case the link change and EEE is enabled or disabled, always try to
re-negotiate this with the link partner.

Fixes: 450b05c15f9c ("net: dsa: bcm_sf2: add support for controlling EEE")
