Subject: [PATCH v6 0/2] mac80211_hwsim: Add PMSR support
Date: Tue, 24 Jan 2023 14:54:28 +0000	[thread overview]
Message-ID: <20230124145430.365495-1-jaewan@google.com> (raw)

Dear Kernel maintainers,

First of all, thank you for spending your precious time for reviewing
my changes, and also sorry for my mistakes in previous patchsets.

Let me propose 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.

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

Many Thanks,

V5 -> V6: Added per CL change history.
V4 -> V5: Fixed style
V3 -> V4: Added detailed explanation to cover letter and per CL commit
          messages, includes explanation of PMSR and FTM.
          Also fixed memory leak.
V1 -> V3: Initial commits (include resends)
