This patch implements various cleanups and fixes aimed to simplify adding AP_VLAN support to qtnfmac driver:
- Remove unused flag field from qlink_intf_info - Add interface type to qlink_cmd_change_sta - Modify qtnf_cmd_send_change_sta: add interface type to command - Fix handling of iftype mask reported by firmware: Firmware sends supported interface type rather than mask. As a result, types field of ieee80211_iface_limit structure may end up having multiple iftype bits set. This leads to WARN_ON from wiphy_verify_combinations.
