Merge git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211-next
Johannes Berg <johannes@sipsolutions.net> says: "This time I have Felix's no-status rate control work, which will allow drivers to work better with rate control even if they don't have perfect status reporting. In addition to this, a small hwsim fix from Patrik, one of the regulatory patches from Arik, and a number of cleanups and fixes I did myself. Of note is a patch where I disable CFG80211_WEXT so that compatibility is no longer selectable - this is intended as a wake-up call for anyone who's still using it, and is still easily worked around (it's a one-line patch) before we fully remove the code as well in the future." Signed-off-by: John W. Linville <linville@tuxdriver.com>
