Introduce Automated Frequency Coordination (AFC) support for UNII-5 and UNII-7
6GHz bands.
Update Transmit Power Envelope (TPE) IE according to the reply from AFC
coordinator on UNII-5 or UNII-7 6GHz bands.
AFCD and AFC hostapd client are tested with AFC DUT Test Harness [0].

Changes since v2:
- multiple fixes testing with AFC DUT Test Harness
Changes since v1:
- use unix socket instead of a tcp one
Changes since rfc:
- move curl connection to a dedicated afc daemon

Lorenzo Bianconi (4):
  hostapd: afcd: add AFC daemon support
  hostapd: export hostapd_is_usable_chans utility routine
  hostapd: ap: add AFC client support
  hostapd: update TPE IE according to AFC

This relies on the Quicktrack agent being installed and run (hopefully
doesn't need a full setup),
so, should we consider adding a basic harness within hostapd itself
that can send responses
based on user input (templates)?

This makes it easier to test without relying on 3rd part components.

Hi Krishna,

in order to test the afc support I think you can just run a simple tcp server
(e.g using nc) replying with a 'static' reply from the afc coordinator. Please
find attached the one I used during the development.
Implementing the full logic of the Quicktrack agent is out of the series scope.

Regards,
Lorenzo

Thanks, this is what I was looking for. IMHO, we should check-in this
file as well
as a reference somewhere or probably a hwsim test.

Got that.
