-rewrite the driver to use the proper in-kernel wireless stack
-instead of using its own.
+Fix the mac80211 port of at76_usb (the proper in-kernel wireless
+stack) and get it included to the mainline. Patches available here:
+
+http://git.kernel.org/?p=linux/kernel/git/linville/wireless-legacy.git;a=shortlog;h=at76
+
+Contact Kalle Valo <kalle.valo@iki.fi> and linux-wireless list
+<linux-wireless@vger.kernel.org> for more information.
