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.
This change allows mac80211_hwsim to report PMSR result. The PMSR result
would come from the wmediumd, where other Wi-Fi device's information is
kept. mac80211_hwsim only need to deliver the result to the userspace.
This change adds HWSIM_CMD_REPORT_PMSR, 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 PMSR result detail, this CL also adds nla policies to
validate incoming reports from wmediumd, and hwsim_rate_info_attributes
to receive rate_info without complex bitrate calculation. (i.e. send
rate_info without adding inverse of nl80211_put_sta_rate()).
