Subject: [PATCH] ax88179_178a: Check for supported Wake-on-LAN modes
Git-commit: 5ba6b4aa9a410c5e2c6417df52b5e2118ea9b467
Patch-mainline: v4.19-rc7
References: bsc#1051510
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.
