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.
