-TODO:
-
-We are working hard on cleaning up the driver. There's sooooooooo much todo
-so instead of editing this file please use the wiki:
-
-http://wireless.kernel.org/en/users/Drivers/ath6kl
-
-There's a respective TODO page there. Please also subscribe to the wiki page
-to get e-mail updates on changes.
-
-IRC:
-
-We *really* need to coordinate development for ath6kl as the cleanup
-patches will break pretty much any other patches. Please use IRC to
-help coordinate better:
