Dear experts,
I am new to Linux kernel, and I have an ambitious goal to run ptp over
wireless (yes I know.. and please don't judge .. )
When I browse code in mac80211, I found function start_pmsr in
ieee80211_ops. At this moment, this function is serving a request
(defined in cfg80211) to start peer measurement, and the request seems
rather FTM specific.
Is there some code available to support the original Timing Measurement?
As I am not interested in localization/ranging, but interested in
synchronization, so the basic TM is enough for me.
Regarding FTM, the current cfg80211_pmsr_ftm_result does not contain the
ToD, ToA timestamps, it only reports the RTT. Is there a proper way to
expose these timestamps to the user space?
Thank you in advance for any guidance,
Wei
