drivers/staging/rtl8723au/TODO

-TODO:
-- find and remove code valid only for 5 HGz. Many of the obvious
-  ones have been removed, but things like channel > 14 still exist.
-- find and remove any code for other chips that is left over
-- convert any remaining unusual variable types
-- find codes that can use %pM and %Nph formatting
-- checkpatch.pl fixes - most of the remaining ones are lines too long. Many
-  of them will require refactoring
-- merge Realtek's bugfixes and new features into the driver
-- switch to use MAC80211
-
-A mac80211 driver for this hardware already was integrated at
-drivers/net/wireless/realtek/rtl8xxxu/
-
-Please send any patches to Greg Kroah-Hartman <gregkh@linuxfoundation.org>,
-Jes Sorensen <Jes.Sorensen@redhat.com>, and Larry Finger <Larry.Finger@lwfinger.net>.
