4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Russell King <rmk+ker...@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.
