[PATCH v4 0/2] mac80211_hwsim: Add PMSR support

[Jaewan Kim <jaewan@google.com>]

Dear Kernel maintainers,

I'm proposing series of CLs for adding PMSR support in the mac80211_hwsim.

PMSR (peer measurement) is generalized measurement between STAs,
and currently FTM (fine time measurement or flight time measurement)
is the one and only measurement.

FTM measures the RTT (round trip time) and FTM can be used to measure
distances between two STAs. RTT is often referred as 'measuring distance'
as well.


Kernel had already defined protocols for PMSR in the
include/uapi/linux/nl80211.h and relevant parsing/sending code are in the
net/wireless/pmsr.c, but they are only used in intel's iwlwifi driver.

This series of CLs are the first attempt to utilize PMSR in the mac80211_hwsim.

CLs are tested with iw tool on Virtual Android device (a.k.a. Cuttlefish).
Hope this explains my CLs.

Many Thanks,
