Subject: [PATCH] NET / skge: Enable WoL by default if supported

From: Rafael J. Wysocki <rjw@...k.pl>

If skge hardware is capable of waking up the system from sleep,
enable magic packet WoL during driver initialisation.

This makes WoL work without calling 'ethtool -s ethX wol g'
for each adapter.
