3.16.62-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Florian Fainelli <f.fainelli@xxxxxxxxx>
commit c4ce446e33d7a0e978256ac6fea4c80e59d9de5f upstream.
The driver currently silently accepts unsupported Wake-on-LAN modes
(other than WAKE_PHY or WAKE_MAGIC) without reporting that to the user,
which is confusing.
Fixes: 2e55cc7210fe ("[PATCH] USB: usbnet (3/9) module for ASIX Ethernet adapters")
