I am curious if there is some sort of igmp or other form of message
that would reliably detect if a switch had a bridge on it. How could
deviceA detect deviceC was a bridge in this case?

deviceA  -> ethernet switch -> deviceB
                    ethernet switch -> deviceC with bridged wifi and ethern=
et
