What is hubCardMap?
A 32-byte bitmap where each bit corresponds to one card slot in the hub, with the least significant bit representing group/slot 1; a '1' means a card is physically present in that slot and '0' means the slot is empty. An admin can poll this to build an inventory of populated vs. free slots without physically opening the chassis.
