Dear Kernel maintainers,
First of all, thank you for spending your precious time for reviewing
my changes.
Let me propose series of patches 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.
Patchset is tested with iw tool on Virtual Android device (a.k.a.
Cuttlefish). Hope this explains my changes.
Many Thanks,

V9 -> V10: Applied reverse xmas tree style (a.k.a. RCS).
V8 -> V9: Removed any wrong words for patch. Changed to reject unknown
PMSR types.
V7 -> V8: Separated patch for exporting nl80211_send_chandef
V6 -> V7: Split 'mac80211_hwsim: handle FTM requests with virtio'
with three pieces
V5 -> V6: Added per patch change history.
V4 -> V5: Fixed style
V3 -> V4: Added detailed explanation to cover letter and per patch commit
messages, includes explanation of PMSR and FTM.
Also fixed memory leak.
V1 -> V3: Initial commits (include resends)
