But I see your interfaces all be added with managed， right?

sure.

apply f019f4dff2e4 ("wifi: ath11k: support 2 station interfaces")
apply 
https://lore.kernel.org/all/20241127022742.4016870-1-quic_yuzha@quicinc.com/

Test steps:
1. add interface
#iw dev wlan0 interface add wlan1 type __ap
#iw dev wlan0 interface add wlan2 type __ap

2.run hostapd
#hostapd hostapd1.conf &
#hostapd hostapd2.conf &

refer hostapd.conf:

interface=wlan1
driver=nl80211
ssid=QSoftAP1
