Subject[PATCH AUTOSEL for 4.14 039/100] phylink: ensure we take the link down when phylink_stop() is called
Date
From: Russell King <rmk+kernel@armlinux.org.uk>

[ Upstream commit 2012b7d6b2868c532f22d9172c8b24611637eb48 ]

Ensure that we tell the MAC to take the link down when phylink_stop()
is called, and that this completes prior to phylink_stop() returns.
