The macro is in ath.git though.

Check and parse Rx MAC timestamp when firmware sets its flag to status variable. 10.4 firmware adds it in Rx beacon frame only at this moment. Drivers and mac80211 may utilize it to detect such clockdrift or beacon collision and use the result for beacon collision avoidance.
