Subject: [PATCH] r8152: Check for supported Wake-on-LAN Modes
Git-commit: f2750df1548bd8a2b060eb609fc43ca82811af4c
Patch-mainline: v4.19-rc7
References: bsc#1051510
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.
Fixes: 21ff2e8976b1 ("r8152: support WOL")
