Subject: net: dsa: start and stop the PHY state machine
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f7f1de51edbdd53b09061d12758cacd9901c363e;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

net: dsa: start and stop the PHY state machine

dsa_slave_open() should start the PHY library state machine for its PHY
interface, and dsa_slave_close() should stop the PHY library state
machine accordingly.
