hwSubslotRowStatus
1.3.6.1.4.1.2011.6.3.3.3.1.10
Only the operation of adding a daughter board, that is, setting createAndGo(4),
is supported. When adding a daughter board, you must set the hwSubslotType object at the same time.
After you add a board by using the hwSlotAdminStatus object in hwSlotTable,
if the board allows you to add a daughter board and the board status (hwSlotOperStatus) is discovery(5),
you can add a daughter board in this way.
