Kalle,
I tested with this firmware: https://github.com/kvalo/ath10k-firmware/blob/master/QCA6174/hw3.0/sdio-4.4.1/firmware-sdio-6.bin_WLAN.RMH.4.4.1-00017-QCARMSWPZ-2

In ath10k_mac_register, it has flag WMI_SERVICE_SPOOF_MAC_SUPPORT enabled.
	if (test_bit(WMI_SERVICE_SPOOF_MAC_SUPPORT, ar->wmi.svc_map)) {
		ar->hw->wiphy->features |=
			NL80211_FEATURE_SCAN_RANDOM_MAC_ADDR;
	}

In ath10k_wow_init, it has flag ATH10K_FW_FEATURE_WOWLAN_SUPPORT, WMI_SERVICE_WOW, WMI_SERVICE_NLO enabled.
int ath10k_wow_init(struct ath10k *ar)
{
	if (!test_bit(ATH10K_FW_FEATURE_WOWLAN_SUPPORT,
		      ar->running_fw->fw_file.fw_features))
		return 0;

	if (WARN_ON(!test_bit(WMI_SERVICE_WOW, ar->wmi.svc_map)))
		return -EINVAL;

	if (test_bit(WMI_SERVICE_NLO, ar->wmi.svc_map)) {
		ar->wow.wowlan_support.flags |= WIPHY_WOWLAN_NET_DETECT;
		ar->wow.wowlan_support.max_nd_match_sets = WMI_PNO_MAX_SUPP_NETWORKS;
	}
