From 237337c230b94e78a5a0f88d1705259ab543fc40 Mon Sep 17 00:00:00 2001 From: Lorenzo Bianconi Date: Sat, 23 Oct 2021 11:10:51 +0200 Subject: mac80211: introduce set_radar_offchan callback Similar to cfg80211, introduce set_radar_offchan callback in mac80211_ops in order to configure a dedicated offchannel chain available on some hw (e.g. mt7915) to perform offchannel CAC detection and avoid tx/rx downtime.
