I'm using elaborate combinations of bridges, tunnels and vlans to make
remote switches many hops away appear as though they're locally

just used to forward traffic between a pair of interfaces. I need the
bridge to behave as much like a dumb 2-port hub as possible,
forwarding LLDP frames that 802.1d-compliant bridges normally drop.

If you turn off STP that is what it does right now. It forwards STP
and 802.1X frames. The patch was only related to turning on STP
and still expecting 802.1X frames to be forwarded (in violation of
the spec).
