To some extent, it is better to think of these as two switches connected to each other, not one switch. The HW switch needs help with STP, but otherwise it is a fully functional and autonomous switch. This is going to make displaying the forwarding database interesting, because the SW bridge fdb and the HW bridge fdb are each subsets of the big picture and possible even contradictory since they are not updated atomically.
