Hello,

When applying this series I am no longer able to start an AP on a DFS channel.
(I don't know specifically which patch though)


Thanks for reporting this. I think non-DFS channel should be working fine right?

Anyways, I'm able to repro the issue locally. Let me investigate further and come back.

After the initial CAC period I get the following kernel message:
	[   45.248441] ath12k_pci 0003:01:00.0: cannot install key for non-existent peer 3a:07:16:d8:00:08
And then hostapd goes in failed state:
	wlan0: interface state UNINITIALIZED->COUNTRY_UPDATE
	ACS: Automatic channel selection started, this may take a bit
	wlan0: interface state COUNTRY_UPDATE->ACS
	wlan0: ACS-STARTED
	wlan0: ACS-COMPLETED freq=5620 channel=124
	wlan0: interface state ACS->DFS
	wlan0: DFS-CAC-START freq=5620 chan=124 sec_chan=1, width=2, seg0=114, seg1=0, cac_time=5s
	wlan0: DFS-CAC-COMPLETED success=1 freq=5620 ht_enabled=0 chan_offset=0 chan_width=5 cf1=5570 cf2=0 radar_detected=0
	wlan0: nl80211: kernel reports: key addition failed
	Interface initialization failed
	wlan0: interface state DFS->DISABLED
	wlan0: AP-DISABLED

Maybe I missed something ? Is there another series this one depends upon that I
should have applied before ?

No known dependency as such.
