Date: Mon, 15 Jan 2007 09:09:17 -0600 From: Harry Coin <hcoin@...omm.com> To: netdev@...r.kernel.org Subject: 3c59x.c patch to 2.6.18 fixing Wake on Lan (WOL) The 3c59x.c in kernel 2.6.18 (and as I see later ones too) attempts to enable PME from the D0 state. The PME config space on Dell Optiplexs for this chip has a zero in the capabilities as it doesn't 'wake from d0'. So the pci_wake call fails, its result is not tested, so no error is reported. The routine changes the wake request from 0 to D3_hot. This fix causes wake on lan (WOL) to work properly on older Dell Optiplex models.
