+What: CONFIG_CFG80211_WEXT
+When: as soon as distributions ship new wireless tools, ie. wpa_supplicant 1.0
+ and NetworkManager/connman/etc. that are able to use nl80211
+Why: Wireless extensions are deprecated, and userland tools are moving to
+ using nl80211. New drivers are no longer using wireless extensions,
+ and while there might still be old drivers, both new drivers and new
+ userland no longer needs them and they can't be used for an feature
+ developed in the past couple of years. As such, compatibility with
+ wireless extensions in new drivers will be removed.
+Who: Johannes Berg <johannes@sipsolutions.net>

What: g_file_storage driver
When: 3.8
Why: This driver has been superseded by g_mass_storage.
