From: Zong-Zhe Yang <kevin_yang@xxxxxxxxxxx> commit 19b815ed71aadee9a2d31b7a700ef61ae8048010 upstream. Chanctx emulation didn't info IEEE80211_CONF_CHANGE_CHANNEL to drivers during ieee80211_restart_hw (ieee80211_emulate_add_chanctx). It caused non-chanctx drivers to not stand on the correct channel after recovery. RX then behaved abnormally. Finally, disconnection/reconnection occurred. So, set IEEE80211_CONF_CHANGE_CHANNEL when in_reconfig.
