Subject: [PATCH v2 mac80211-next 0/6] add offchannel radar chain support
Date: Sat, 23 Oct 2021 11:10:49 +0200 [thread overview]
Message-ID: <cover.1634979655.git.lorenzo@kernel.org> (raw)
Introduce the capability to configure a dedicated chain available for radar
detection on some hw (e.g. mt7915). This chain can't be used to transmit or
receive frames and it is bounded to a running wdev.
Offchannel radar/CAC detection allows to avoid the CAC downtime switching
to a different channel during CAC detection on the selected radar channel.
hostapd will implement the logic to select and configure the monitored
channel.
Changes since v1:
- introduce offchanel chain ownership through offchan_radar_wdev pointer
- spilt patch 1/5 in cfg80211 and mac80211 part
- move cac work from driver code to cfg80211
Changes since rfc:
- rely on NL80211_CMD_RADAR_DETECT netlink msg to configure offchannel radar
chain
Lorenzo Bianconi (6):
cfg80211: introduce set_radar_offchan callback
mac80211: introduce set_radar_offchan callback
cfg80211: introduce the capability to configure offchannel CAC
detection
cfg80211: introduce cfg80211_cac_offchan_event routine
cfg80211: introduce offchannel cac delayed work
cfg80211: introduce NL80211_EXT_FEATURE_RADAR_OFFCHAN feature flag
