+This patch backports the struct net_device_ops changes added
+on 2.6.29. It also backports the namespace changes added
+through net/wireless/wext.c. Note that there is another
+patch file which also addresses netns changes, we leave
+them separate as there is no easy way to split the stuff
+without creating a headache on maintenance of the pathes.

+Your current kernels configuration (.config and linux/autoconf.h)

+=======================
+
+You must have a really good reason to be adding files
+in this directory. Your reasoning should either match the
+explanation already present on the top of each patch file
+or you should add your own.
+
+We try to avoid having patch files because:
+
+ * Its a pain in the ass to maintain them.
+
+ * Most backport changes can be pulled off through
+ some macro magic or new files which implement
+ the new functionality on the old kernels.
