Hello, and welcome!
The bridge(4) man page states that the driver follows IEEE 802.1D-2004, and BDPUs are defined in Section 9.3 of that standard. But I do not see BPDU mentioned in that man page, nor are they mentioned in the ifconfig(8) man page, nor is the acronym mentioned in the change log.
The source code may mention BPDUs, but I currently do not have access to the source tree from behind the Great Corporate Firewall (TM) we have at $DAYJOB.
