What: Code that is now under CONFIG_WIRELESS_EXT_SYSFS
(in net/core/net-sysfs.c)
When: 3.5
Why: Over 1K .text/.data size reduction, data is available in other
ways (ioctls)
Who: Johannes Berg <johannes@sipsolutions.net>
---------------------------
What: sysfs ui for changing p4-clockmod parameters
When: September 2009
Why: See commits 129f8ae9b1b5be94517da76009ea956e89104ce8 and

----------------------------
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Why: This driver has been superseded by g_mass_storage.
