	From wireshark, I noticed that when send an data frame , the
duration of frame control is fixed at 60 , no matter the frame length is 100
bytes or 1000 bytes.

	It seems this value is calculated in firmware and should be correct.
But I don't know why. And this value can be set in mac80211?

Duration calculation is broken for ath9k_htc.
