Add a patch to fix Intel E100 wake-on-lan problems.

[ipfire-2.x.git] / src / patches / suse-2.6.27.31 / patches.rpmify / cloneconfig.diff

From: Andreas Gruenbacher <agruen@suse.de>
Subject: Add ``cloneconfig'' target

Cloneconfig takes the first configuration it finds which appears
to belong to the running kernel, and configures the kernel sources
to match this configuration as closely as possible.
