Subject: [PATCH -next 1/2] gianfar: Implement proper, per netdevice wakeup management
Date: Wed, 28 Jan 2009 23:38:54 +0300	[thread overview]
Message-ID: <20090128203854.GA14693@oksana.dev.rtsoft.ru> (raw)

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.
