From mboxrd@z Thu Jan 1 00:00:00 1970 From: akpm@linux-foundation.org Subject: [patch 3/4] WOL bugfix for 3c59x.c Date: Tue, 16 Oct 2007 14:24:09 -0700 Message-ID: <200710162124.l9GLO9t6017971@imap1.linux-foundation.org> Cc: netdev@vger.kernel.org, akpm@linux-foundation.org, klassert@mathematik.tu-chemnitz.de, hcoin@n4comm.com To: jeff@garzik.org Return-path: Received: from smtp2.linux-foundation.org ([207.189.120.14]:35033 "EHLO smtp2.linux-foundation.org" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S933685AbXJPVZH (ORCPT ); Tue, 16 Oct 2007 17:25:07 -0400 Sender: netdev-owner@vger.kernel.org List-Id: netdev.vger.kernel.org From: Steffen Klassert Some NICs (3c905B) can not generate PME in power state PCI_D0, while others like 3c905C can. Call pci_enable_wake() with PCI_D3hot should give proper WOL for 3c905B.
