From 3871c3876f8084a2f40ba3c3fc20a6bb5754d88d Mon Sep 17 00:00:00 2001 From: Michael Stapelberg Date: Mon, 11 Mar 2013 13:56:45 +0000 Subject: mv643xx_eth with 88E1318S: support Wake on LAN This has been tested on a qnap TS-119P II. Note that enabling WOL with "ethtool -s eth0 wol g" is not enough; you also need to tell the PIC microcontroller inside the qnap that WOL should be enabled by sending 0xF2 with qcontrol(1) and you have to disable EUP ("Energy-using Products", a European power-saving thing) by sending 0xF4.
