Subject: net: dsa: bcm_sf2: Ensure we re-negotiate EEE during after link change
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=94de6f2ffb3de28f4a6c92a52e8f8cdcb7046847;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

net: dsa: bcm_sf2: Ensure we re-negotiate EEE during after link change

[ Upstream commit 76da8706d90d8641eeb9b8e579942ed80b6c0880 ]

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