Setter method for interface_type, mapped from YANG variable /brocade_xstp_ext_rpc/get_stp_brief_info/output/spanning_tree_info/rstp/port/interface_type (enumeration)
    If this variable is read-only (config: false) in the
    source YANG file, then _set_interface_type is considered as a private
    method. Backends looking to populate this variable should
    do so via calling thisObj._set_interface_type() directly.

    YANG Description: The type of the interface. An 'unknown' type 
represents error scenario and should not be used.
