FS#3968 - Incorrect channel reported by ath10k-*-htt firmware

Supply the following if possible:
- Device problem occurs on
- Software versions of OpenWrt/LEDE release, packages, etc.
- Steps to reproduce

 

Devices: Archer C7 v2, Linksys EA8300
OpenWRT: 21.02 rc4

Steps:

1. (Archer) Replace default ath10k-firmware-qca988x-ct firmware with ath10k-firmware-qca988x-ct-full-htt

opkg remove ath10k-firmware-qca988x-ct && opkg install ath10k-firmware-qca988x-ct-full-htt && reboot

(EA8300) Replace default ath10k-firmware-qca4019-ct firmware with ath10k-firmware-qca4019-ct-htt

opkg remove ath10k-firmware-qca4019-ct && opkg install ath10k-firmware-qca4019-ct-htt  && reboot

2. Set wireless device to channel 36 and create an ssid
cat /etc/config/wireless:

config wifi-device 'radio2'
	option type 'mac80211'
	option hwmode '11a'
	option path 'platform/soc/a800000.wifi'
	option htmode 'VHT80'
	option cell_density '0'
	option channel '36'

config wifi-iface 'wifinet6'
	option device 'radio2'
	option mode 'ap'
	option ssid 'ssid'
	option encryption 'sae'
	option key 'xxxxxxx'
	option ieee80211w '2'
	option wds '1'
	option network 'lan'

3. iwinfo and luci reports operation on channel 40:
Archer:
wlan0-1 ESSID: “ssid”

        Access Point: XX:XX:XX:XX:XX
        Mode: Client  Channel: 40 (5.200 GHz)
        Center Channel 1: 42 2: unknown
        Tx-Power: 20 dBm  Link Quality: 52/70
        Signal: -58 dBm  Noise: -102 dBm
        Bit Rate: 351.0 MBit/s
        Encryption: WPA3 SAE (CCMP)
        Type: nl80211  HW Mode(s): 802.11nac
        Hardware: 168C:003C 0000:0000 [Qualcomm Atheros QCA9880]
        TX power offset: none
        Frequency offset: none
        Supports VAPs: yes  PHY name: phy0

EA8300:
wlan2 ESSID: “ssid”

        Access Point: XX:XX:XX:XX:XX
        Mode: Master  Channel: 40 (5.200 GHz)
        Center Channel 1: 42 2: unknown
        Tx-Power: 23 dBm  Link Quality: 31/70
        Signal: -79 dBm  Noise: -105 dBm
        Bit Rate: 866.7 MBit/s
        Encryption: WPA3 SAE (CCMP)
        Type: nl80211  HW Mode(s): 802.11nac
        Hardware: 168C:003C 168C:4019 [Qualcomm Atheros IPQ4019]
        TX power offset: none
        Frequency offset: none
        Supports VAPs: yes  PHY name: phy2

My wifi analyzers show that the signal is actually on channel 36, it is just reported incorrectly by the firmware.
