Subject: [PATCH -next 1/2] gianfar: Implement proper, per netdevice wakeup management

From: Anton Vorontsov <[email-masked]>
Date: Wed, 28 Jan 2009 23:38:54 +0300

This patch implements wakeup management for the gianfar driver.

The driver should set wakeup enable if WOL is enabled, so that
phylib won't power off an attached PHY.
