Check and set Rx MAC timestamp when firmware indicates it.
Firmware adds it in Rx beacon frame only at this moment.
Driver and mac80211 may utilize it to detect such clockdrift
or beacon collision and use the result for beacon collision
avoidance.

Oh.. I feel bad for noticing this so late.
review is always appreciated.
I think this can be
represented with a mere __le64 and then accessed via le64_to_cpu().
sent new patch based on your comment.
Thanks,
Peter
