Subject[PATCH 4.4 02/76] net: bcmgenet: Do not suspend PHY if Wake-on-LAN is enabled
Date
4.4-stable review patch.  If anyone has any objections, please let me know.

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

From: Florian Fainelli <f.fainelli@gmail.com>


[ Upstream commit 5371bbf4b295eea334ed453efa286afa2c3ccff3 ]

Suspending the PHY would be putting it in a low power state where it
may no longer allow us to do Wake-on-LAN.

Fixes: cc013fb48898 ("net: bcmgenet: correctly suspend and resume PHY device")
