     * @group:       	4.4.7.1 Discarding State
     *
     * @description: 	Discarding ports do not participate in the active topology and do not learn MAC addresses.
     * 					• Discarding state: the state includes three states of the disable, blocking and listening of STP.
     * 					• Port setting: transmit enable = “0”, receive enable = “0”, learning disable = “1”.
     * 					• Software action: The host processor should not send any packets to the port. The switch may still send specific
     * 					packets to the processor (packets that match some entries in the static table with “overriding bit” set) and the pro-
     * 					cessor should discard those packets. When the port's learning capability (learning disable = '1') is disabled, port
     * 					related entries in the ALU table and static MAC table can be rapidly flushed.
