For example, - MLO_2_PLUS_0_1RF is 1 link with 2SS rate, and enable one RF component. - MLO_1_PLUS_1_1RF is 2 links with 1SS rate for each, and enable one RF component that can support two paths. By default, we set the mode to legacy MLO_DBCC_NOT_SUPPORT (don't support MLO and DBCC yet), and later we will introduce logic to change the mode.
