Arf maybe I wasn't clear, my bad.

I have a running AP on wlan0. I constantly monitor connected stations infos
using 'iw dev wlan0 station dump' on the side in another terminal, and then I
add a monitor interface with the above steps, and thats when I see that the
stations connected to my AP have frozen values in station dump.

I suspect that ath12k_dp_tx_htt_rx_monitor_mode_ring_config() should reset the
rx filters to ath12k_mac_mon_status_filter_default when disabling monitor. But
I'm not so sure, you guys know better.
