This is a question best directed at the manufacturer to see how their
device handles packets. That being said, as long as the packets are not
manipulated, the bridges do not need to know any other information
other than to send it in one port and out the other.

There is one caveaut to this, though. If you wish to be able to manage
the device from the network, or pass any data to/from the device
specifically, you must enable the proper protocols.

Hope that was helpful.
