wext: make sysfs bits optional and deprecate them
The /sys/class/net/*/wireless/ direcory is, as far as I know, not used by anyone. Additionally, the same data is available via wext ioctls. Hence the sysfs files are pretty much useless. This patch makes them optional and schedules them for removal. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Cc: Jean Tourrilhes <jt@hpl.hp.com> Signed-off-by: John W.
