From 9eaabc0a77799b3563a5be757e551ae7463d2706 Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Fri, 28 Sep 2018 16:18:54 -0700 Subject: [PATCH] r8152: Check for supported Wake-on-LAN Modes [ 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.
