[ath9k-devel] Dirty Laundry List

[Luis R. Rodriguez <lrodriguez@atheros.com>]

Moving this discussion out to the public list. Guys this is our
latest TODO list. We welcome people from the community to take up items
here, but please let us know if you are going to work on something.

I'll be tackling the MacBook pro swiotlb issue, I think this should be
fixed now, but not sure, needs a MacBook Pro 3.1 tester. I also already
started working on the ath9k regulatory scrub. Essentially we'll be
relying on CRDA for 11d instead of the EEPROM so this is a huge major
cleanup. Also there is a lot of potential to share this work with ath5k
code. One option which Jouni suggested was a module we can share between
ath9k/ath5k, maybe some sort of ath_common.ko or the like and first
stash in there reg stuff. Maybe later add more shared stuff as we go.
