From 9c734b2769a73eea2e9e9767c0e0bf839ff23679 Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Fri, 28 Sep 2018 16:18:55 -0700 Subject: [PATCH] smsc75xx: Check for Wake-on-LAN modes 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.
