Subject: [PATCH AUTOSEL 4.4 17/25] r8152: Check for supported Wake-on-LAN Modes

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

[ Upstream commit f2750df1548bd8a2b060eb609fc43ca82811af4c ]

The driver does not check for Wake-on-LAN modes specified by an user,
but will conditionally set the device as wake-up enabled or not based on
that, which could be a very confusing user experience.
