I took some time to debug this in my 10.1 CT firmware. It appears that the problem is the ANQP queries may be destined for APs that the station is not currently connected to. So, the firmware cannot find the peer, and then it just fails to put the management frame on the air. I have fixed my CT firmware to use the 'bss-peer' when the real peer for a mgt-frame cannot be found. That appears to work. Unless upstream firmware does something similar, I think ANQP (GAS) queries are going to remain broken on ath10k. I am not sure of any sane way to do a work-around in the driver, unless you want to add fake peers and then make them go away sometime later (when you assume the mgt frame has been properly put on the air). A simple test case is to use recent wpa_cli: > anqp_get 00:0e:8e:f8:73:96 1 OK <3>GAS-QUERY-START addr=00:0e:8e:f8:73:96 dialog_token=0 freq=5180 <3>GAS-QUERY-DONE addr=00:0e:8e:f8:73:96 dialog_token=0 freq=5180 status_code=0 result=SUCCESS <3>ANQP-QUERY-DONE addr=00:0e:8e:f8:73:96 result=SUCCESS > That MAC addr is an AP that the station is NOT connected to. Even if you have no ANQP support in the AP, this should still put a packet on the air I believe...so you should be able to do simple testing with a sniffer.
