Hi,

I have looked through the individual hardware drivers, but there seems to be 
no way of getting an accurate time when an individual packet preamble hits the 
antenna.

For RX, most drivers support a RX timestamp based on the TSF and put this into  
struct ieee80211_rx_status -> mactime. For TX, I found nothing related.

Kind regards,

Stefan
