Analyze and fix the following issue in the Linux kernel code: Fix forcedeth hibernate/wake-on-lan problems
Problem Details: This patch is the minimal amount of code needed to support wake-on-lan in platform mode properly (i.e. "ethtool -s eth0 wol g" is sufficient, no additional magic needed) for me. This is derived from David Brownells patch (http://lists.laptop.org/pipermail/devel/2007-April/004691.html). However I decid...
