Hi Luis,
I find the wireshark can only capture 11b/g packets but any 11n packets over
my ar9283 card, and I can confirm I have set HT40+ to make it work in 11n mode.
wireshark : 1.2.2
kernel : 2.6.32-rc6
I don't know what is wrong with it, and could ath9k work well in monitor
mode of 11n? or other reason?
Look forward to your reply.
Thanks,

Oh, I see.
Is there any patch which may let mac80211 forward HT packets to
monitor interface now?
If there is, where could I find it?

Matteo added a suggested field for radiotap for MCS rates:
http://www.radiotap.org/suggested-fields/MCS
If approved it could mean then parsing MCS rates.

It will forward all frame that it gets from the driver, just not tell
you it was an HT frame in radiotap since there's no way to -- you'll see
a frame without rate information.

I don't know exactly, but a while ago there was a discussion about how
to represent HT rates in Radiotap. AFAIK mac80211 refuses to forward
HT packets to monitor interfaces as they don't have a valid CCK or
OFDM rate.
