Subject: [PATCH 4.14 110/146] phylink: ensure AN is enabled

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

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

From: Russell King <rmk+kernel@...linux.org.uk>


[ Upstream commit 74ee0e8c1bf9925c59cc8f1c65c29adf6e4cf603 ]

Ensure that we mark AN as enabled at boot time, rather than leaving
it disabled.  This is noticable if your SFP module is fiber, and
it supports faster speeds than 1G with 2.5G support in place.
