Enable NTB continuous ranging with configurable timing and measurement
parameters as per the Wi-Fi Alliance specification "Proximity Ranging
(PR) Implementation Consideration Draft 1.9 Rev 1, section 5.3". Add
new FTM request attributes for min/max time between measurements,
nominal time (mandatory for NTB), AW duration, and total measurement
count.
Add NL80211_PMSR_PEER_ATTR_REQ_TYPE attribute using the new
nl80211_peer_measurement_ftm_req_type enum to allow userspace to
specify the ranging request type per peer:
- NL80211_PMSR_FTM_REQ_TYPE_INFRA: STA-to-AP or AP-to-STA ranging
(default if attribute is absent)
- NL80211_PMSR_FTM_REQ_TYPE_PD: peer-to-peer ranging
Validate the request type against the device TYPE_CAPS capabilities
advertised via NL80211_PMSR_FTM_CAPA_ATTR_TYPE_CAPS. Reject PD
requests if the device does not advertise PD support.
Reject PD requests that set trigger-based ranging, as TB ranging is
not compatible with peer-to-peer proximity detection.
Add ftms_per_burst limit of 4 for PD NTB ranging requests.
