+---------------------------
+
+What: Code that is now under CONFIG_WIRELESS_EXT_SYSFS
+ (in net/core/net-sysfs.c)
+When: After the only user (hal) has seen a release with the patches
+ for enough time, probably some time in 2010.
+Why: Over 1K .text/.data size reduction, data is available in other
+ ways (ioctls)
