    Even the initial single/dual stream values will be overridden later when
    issue link quality command; but still make sense not to use hard-code
    value during initialization. Single/Dual stream mask are used to indicate the
    best antenna for SISO/MIMO; different NIC has different tx antenna
    configuration; so the parameter need to based on the valid tx antenna.
    
    1x2 device: single tx antenna available, only SISO is valid
    configuration, but still need to set up MIMO configuration, so set it up
    with antenna A & B as default.
    2x2 device: two tx antenna available, dual_stream will use both valid
    antenna.
    
    3x3 device: three tx antenna available, skip the first antenna and
    choice the second and third antenna for dual_stream.
