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.
Support is also added for Out-of-Band peer discovery where USD is
handled by an external application, and per-peer PMK and password
configuration via PR_PASN_START for authenticated PASN without
prior NAN USD discovery.

Kernel Changes are merged into wireless-next tip.

---
Changes in v3:
- The earlier supplicant patchset (v2) was aligned with a previous
  kernel patchset series. Since that kernel series has now been merged,
  the supplicant has been updated again (v3) to align with the current
  wireless-next.
- Fixed several bugs identified during internal testing. Introduced
  new patches in this series.
- Added support for Out-of-Band (OOB) peer discovery: when USD
  service discovery is handled by an external application and
  PASN is triggered separately via PR_PASN_START, a minimal peer
  entry is created automatically to allow PASN to proceed without
  prior NAN USD discovery.
---
Changes in v2:
- Added the correct NL attributes.
- Refactored dependent code paths to reflect the updated NL
  attribute handling.

I applied patches 1-13 and 16-17. I'll continue reviewing patches 21,
23-24, 26-29, 32-33, 39, 41, 44, 46. The I dropped other patches based
on open questions and dependencies to the patches with open questions.

I applied patches 21, 23-24, 26-27, 29, 32, 39, 41, 44, 46. I have no
patches remaining in my queue, i.e., other patches had either open
questions or dependencies to the patches with open questions.
