You dropped Peter and the linux-wireless list from your reply, adding
them back.

Thanks! Based on that I think this is probably what we need:
(2400 - 2483.5 @ 40), (23)
(5150 - 5250 @ 80), (23), AUTO-BW
(5250 - 5350 @ 80), (20), DFS, AUTO-BW
(5470 - 5725 @ 160), (20), DFS
(5725 - 5835 @ 80), (23)
Peter, if that looks good to you please send a v3 patch.
Thanks,
Seth

DFS bandwidth is correct although the rules(radar types and etc.) are
different from JP, but no plan yet to add KR rules to DFS (requires
kernel space patches).

It looks good to me, too. I'll do v3.
Thanks,
