[RFC PATCH 00/23] PR: Add nl80211 support and ranging for Proximity Detection

[Peddolla Harshavardhan Reddy]

wpa_supplicant already had PASN authentication support for
Proximity Ranging (PR). This series adds the missing nl80211
driver support and ranging to complete the PD (Proximity
Detection) flow.

It introduces a dedicated PD virtual interface (NL80211_IFTYPE_PD)
with its own MAC address, updates nl80211_copy.h with the
proposed kernel API additions for PD, improves driver capability
parsing with dedicated PR-specific flags, extends the set_key
path to carry LTF key seeds for secure ranging, and wires up
peer measurement start and result handling through the nl80211
driver. The existing PR_PASN_START control interface command is
extended with the full set of EDCA, NTB, and proximity threshold
parameters and rerouted through wpas_pr_pasn_trigger() to drive
the complete PASN-then-ranging flow in a single step.

The proposed wireless-next changes that are used here are:
