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:
