AP/VLAN hack and broadcast breakage on QCA988X

[pxnky]

Running a patched openwrt 19.07.6 on a Unifi AP AC Pro and dynamic vlans were not working on the 5ghz radio (ath10k) but were working on the 2.4ghz radio (ath9k).. In an attempt to fix it I found #134 and applied this patch:

@@ -9995,7 +9944,10 @@ int ath10k_mac_register(struct ath10k *a
                goto err_dfs_detector_exit;
        }

-       if (test_bit(WMI_SERVICE_PER_PACKET_SW_ENCRYPT, ar->wmi.svc_map)) {
+       if (test_bit(WMI_SERVICE_PER_PACKET_SW_ENCRYPT, ar->wmi.svc_map) ||
+           test_bit(ATH10K_FW_FEATURE_CONSUME_BLOCK_ACK_CT, ar->normal_mode_fw.fw_file.fw_features)) {
+                       /* assume enough raw tx support for VLAN if a recent CT
+                        * firmware is detected. */
                ar->hw->wiphy->interface_modes |= BIT(NL80211_IFTYPE_AP_VLAN);
                ar->hw->wiphy->software_iftypes |= BIT(NL80211_IFTYPE_AP_VLAN);
        }

This fixed dynamic vlans for me but now I've realized broadcast traffic is not passing on that radio.

Anything I can try/test or more information I can supply would be appreciated! Thanks!
