Yeah I saw this, but we also do in ath5k_hw_get_frame_duration():
/* subtract difference between long and short preamble */
dur = le16_to_cpu(raw_dur);
if (shortpre)
dur -= 96;
I assume (I didn't write this code) that it was done this way because
we don't always have a vif to pass into the generic code.
