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, -- 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.
