Introduce background radar/CAC detection through a dedicated off-channel
chain available on some hw (e.g. mt7915).
Background radar/CAC detection allows to avoid the CAC downtime
switching on a different channel during CAC detection on the selected
radar channel.

Lorenzo Bianconi (9):
  Sync include/uapi/linux/nl80211.h with mac80211-next.git
  DFS: introduce dfs_set_valid_channel utility routine
  DFS: add capability select radar-only channels
  nl80211: report background radar/cac detection capability
  DFS: configure background radar/cac detection.
  DFS: introduce hostapd_dfs_request_channel_switch routine
  DFS: enable CSA for background radar detection
  DFS: switch to background radar channel if available
  DFS: introduce radar_background parameter to config file

Thanks, applied patches 2-4 with some cleanup (mainly, replaced the
int flags parameter in 3/9 with an enum to make the code more readable.
Patch 1 changes are covered by another commit.

These have open questions or dependencies on patches with open
questions.
