====================
pull-request: ieee802154-next 2023-02-20

Miquel Raynal build upon his earlier work and introduced two new
features into the ieee802154 stack. Beaconing to announce existing
PAN's and passive scanning to discover the beacons and associated
PAN's. The matching changes to the userspace configuration tool
have been posted as well and will be released together with the
kernel release.

Arnd Bergmann and Dmitry Torokhov worked on converting the
at86rf230 and cc2520 drivers away from the unused platform_data
usage and towards the new gpiod API. (I had to add a revert as
Dmitry found a regression on an already pushed tree on my side).

Changes since v1 (pull request 2023-02-02)
- Netlink API extack and NLA_POLICY* usage as suggested by Jakub
- Removed always true condition found by kernel test robot
- Simplify device removal with running background job for scanning
- Fix problems with beacon sending in some cases by using the MLME
  tx path
