    Setter method for port_control, mapped from YANG variable /interface/fortygigabitethernet/dot1x/port_control (enumeration)
    If this variable is read-only (config: false) in the
    source YANG file, then _set_port_control is considered as a private
    method. Backends looking to populate this variable should
    do so via calling thisObj._set_port_control() directly.

    YANG Description: This leaf specifies the port state.
'auto' enables 802.1x authentication. The port 
moves to authorized state only after successful 
authentication. 'force-authorized' disables 802.1x
and port moves to authorized state without any 
authentication. 'force-unauthorized' causes the
port to remain in the unauthorized state,
ignoring all attempts by the client to 
authenticate.
