[PATCH v3 0/3] dbus: expose per-BSS RSN capabilities

[Aleksman4o <aleksman4o@gmail.com>]

From: Aleks Man <aleksman4o@gmail.com>

James, thanks for confirming that extending BasicServiceSet is a
reasonable approach.

Network.Type intentionally represents WPA2-Personal, WPA3-Personal, and
transition networks as "psk".  This series exposes the RSN information
that iwd already retains for each BSS so consumers can distinguish those
networks without changing the existing Network API.

The optional BasicServiceSet.RSN dictionary uses the same KeyMgmt,
Pairwise, and Group fields and values as wpa_supplicant's BSS.RSN
property.  NetworkManager can therefore reuse its existing parser rather
than add another translation layer.  Older consumers ignore the optional
property, and consumers can retain their Network.Type fallback for older
iwd versions.

A corresponding NetworkManager series reads and combines the per-BSS
capabilities for its synthetic ESS access point.  It will be submitted
separately after this API series.

Validation:

  - iwd builds successfully with make -j4.
  - On a physical WPA2/WPA3 transition network, an initial PSK connection
    was reported as WPA2.  After changing the saved profile to SAE, a
    disconnect/reconnect through the stock Plasma applet completed without
    a password prompt and was reported as WPA3-SAE.
  - Cycling Wi-Fi subsequently auto-connected the SAE profile and kept it
    visible as connected in the applet.
  - The upstream CI auto-t runner passed the v2 series.

Changes in v3:
  - Shorten the auto-t filename so the generated patch metadata complies
    with GitLint's 80-column limit.  There are no code changes.

Changes in v2:
  - Resend with git-send-email after the Gmail web client corrupted the
    inline v1 patches.  There are no code changes.
