From 582c1b538fb47a2d6a41dbdadb031086c49446c1 Mon Sep 17 00:00:00 2001 From: Anna Neal Date: Mon, 20 Oct 2008 16:46:56 -0700 Subject: libertas: Fine grained configuration of wake-on-lan. Based on a patch from Shailendra Govardhan . This patch allows implementation of more specific wake-on-lan rules than those of ethtool. Please note that only firmware 5.110.22.p20 and above supports this feature. This patch only implements the driver/firmware interface, not the userspace/driver interface.
