      mac80211_hwsim: add PMSR report support via virtio · 2af3b2a6
      Jaewan Kim authored
      PMSR (a.k.a. peer measurement) is generalized measurement between two
      devices with Wi-Fi support. And currently FTM (a.k.a. fine time measurement
      or flight time measurement) is the one and only measurement.
      
      Add the necessary functionality to allow mac80211_hwsim to report PMSR
      result. The result would come from the wmediumd, where other Wi-Fi
      devices' information are kept. mac80211_hwsim only need to deliver the
      result to the userspace.
      
      In detail, add new mac80211_hwsim attributes HWSIM_CMD_REPORT_PMSR, and
      HWSIM_ATTR_PMSR_RESULT. When mac80211_hwsim receives the PMSR result with
      command HWSIM_CMD_REPORT_PMSR and detail with attribute
      HWSIM_ATTR_PMSR_RESULT, received data is parsed to cfg80211_pmsr_result and
      resent to the userspace by cfg80211_pmsr_report().
      
      To help receive the details of PMSR result, hwsim_rate_info_attributes is
      added to receive rate_info without complex bitrate calculation. (i.e. send
      rate_info without adding inverse of nl80211_put_sta_rate()).
