From 1a1769f32349a188db48cf81fe306b6f841fc246 Mon Sep 17 00:00:00 2001 From: Steffen Klassert Date: Tue, 16 Oct 2007 14:24:09 -0700 Subject: [PATCH] WOL bugfix for 3c59x.c 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.
