Wake on Lan and pci_enable_wake()

Hello, As far as I know, Wake On Lan is disabled by default in Linux. Now I try this on p2p1: ethtool -i p2p1 ... driver: r8169 ... ethtool p2p1 .. Wake-on: g ... this means, according to the man, that Wake on Lan is enabled for MagicPacket packets on p2p1 Now I looked in the code of the driver and I cannot see anywhere a call to pci_enable_wake(); see drivers/net/ethernet/realtek/r8169.c So any ideas how come that the Wake on Lan is enabled for this driver after boot ? rgs, Andy
