commit 0b753722754ae66067408e15835e1d66161dcb41

    hostapd: add wmm qos map set by default
    
    This implements the mapping recommendations from RFC8325, with an
    update from RFC8622. This ensures that DSCP marked packets are properly
    sorted into WMM classes.
    The map can be disabled by setting iw_qos_map_set to something invalid
    like 'none'
