Hi, all,
I'm using iwi(Intel(R) PRO/Wireless 2915ABG).
iwi driver does not support 802.11j channels (34, 38, 42, 46) which channles
are used in Japan.
# a channel set, 34, 38, 42, 46 is called 'J52' in Japan.
So, I fix iwi to support 802.11j channels.
But it is no good fix.
I think it is better to get supported channels list from iwi firmware.
Does anybody know how to get supported channels list from iwi firmware?
Thanks,
