Hello,

There might be something wrong with this series.

I applied it on top of ath-pending-202501150104 + the "ath12k: Add peer extended
Rx statistics debugfs support" and now 'iw dev wlan0 station dump' shows me
that the RSSI value seems to not be updated anymore after I stop a monitor
interface on the same phy.

Steps to reproduce:
iw phy phy0 interface add mon0 type monitor
ip link set mon0 up
# then just for 1 sec but it might not be usefull at all
tcpdump -nepi mon0
ip link set mon0 down
watch -n1 iw dev wlan0 station dump
# 'signal' seems to not be updating anymore, maybe some other fields too ?

Don't know if this is from this series or something else broken before, but as
we could not add a monitor interface before, I could not see it.

There still is a possibility that I messed something up while applying it so I
would greatly appreciate if you could check it.

This is on split-phy QCN9274 hw2.0 PCI WLAN.WBE.1.3.1-00173-QCAHKSWPL_SILICONZ-1

Thanks
