From b61303219cb1b21c00fe9b4eed58327dc2d3df2f Mon Sep 17 00:00:00 2001 From: Anton Vorontsov Date: Thu, 29 Jan 2009 17:31:13 -0800 Subject: [PATCH] gianfar: Fix Wake-on-LAN support commit 6370fe8e2204a84305398b9385caac969cdd20f8 ("phy: power management support") caused a regression in the gianfar driver. Now phylib turns off PHY power during suspend, and thus WOL doesn't work anymore. This patch workarounds the issue by enabling wakeup in the MDIO device, i.e. just restores the old behaviour for the gianfar driver. Note that this way all PHYs on a given MDIO bus won't be turned off during suspend, which isn't good from the power saving point of view. A proper, per netdevice wakeup management support will need a bit reworked phylib suspend/resume logic. Signed-off-by: Anton Vorontsov Signed-off-by: David S.
