Subject: bgmac: start/stop PHY on netdev open/stop
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4e34da4d4252f93a7bc66017a7577afb03c3cb8e;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

bgmac: start/stop PHY on netdev open/stop

I've realized that I need to call ethtool command to get Ethernet
working after booting. Ex call: ethtool -s eth0 autoneg on
It was fixing Ethernet even if auto-negotiation was already on.

Adding calls to phy_start and phy_stop look like a real solution.
