Subject: [PATCH mac80211-next 0/4] add offchannel radar chain support
Date: Tue, 19 Oct 2021 13:59:03 +0200 [thread overview]
Message-ID: <cover.1634644309.git.lorenzo@kernel.org> (raw)
Introduce the capability to configure a dedicated chain available for radar
detection on some hw (e.g. mt7915). The driver is supposed to implement CAC
management in sw or fw while hostapd will implement the logic to select and
configure the monitored channel.
Using a dedicated chain to perform the CAC, the AP can avoid the CAC downtime
switching to a new DFS channel.
Changes since rfc:
- rely on NL80211_CMD_RADAR_DETECT netlink msg to configure offchannel radar
chain
Lorenzo Bianconi (4):
mac80211: introduce set_radar_offchan callback
cfg80211: introduce NL80211_ATTR_RADAR_OFFCHAN netlink attribute
cfg80211: introduce cfg80211_cac_offchan_event routine
cfg80211: introduce NL80211_EXT_FEATURE_RADAR_OFFCHAN feature flag
