Subject: [PATCH net 3/7] lan78xx: Check for supported Wake-on-LAN modes
Date: Mon, 24 Sep 2018 13:54:16 -0700 [thread overview]
Message-ID: <20180924205420.31309-4-f.fainelli@gmail.com> (raw)
In-Reply-To: <20180924205420.31309-1-f.fainelli@gmail.com>
The driver supports a fair amount of Wake-on-LAN modes, but is not
checking that the user specified one that is supported.
Fixes: 55d7de9de6c3 ("Microchip's LAN7800 family USB 2/3 to 10/100/1000 Ethernet device driver")
