wifi: cfg80211: allow suppressing FTM result reporting for PD requests
Proximity detection often does not require detailed ranging
measurements, yet userspace currently receives full FTM results for
every request, causing unnecessary data transfer, host wakeups, and
processing overhead.
Add an optional control to suppress ranging result reporting for
peer-to-peer PD requests. Introduce the
NL80211_PMSR_FTM_REQ_ATTR_PD_SUPPRESS_RESULTS flag; when set with a
PD request, the device may perform the measurements (e.g. when acting
as RSTA) but must not report the measurement results to userspace.
Validate that the flag is only accepted when request_type is set to
NL80211_PMSR_FTM_REQ_TYPE_PD, reject otherwise.
