@Kyle Evans:

Patch did not do the trick. I can try to tcpdump this weekend (perhaps) to
prove it, but behavior is same as before.

Also I note that the patch adds the call to ETHER_BPF_MTAP at a different place
than in HEAD -- in the patch it adds right before bridge_enque, but in HEAD
(but not in 12.1) the call is higher, outside the if{} block:

https://github.com/freebsd/freebsd/blob/0f0a35a04846fc4f4bdb6caa2852336d7de9447d/sys/net/if_bridge.c#L2058-L2060

I am sure this is intended but just thought I'd mention here for others.

Anyway, thanks for looking at this. If you can think of other diagnostics I can
do that would be helpful, let me know.
