I would like to filter Spanning-Tree Protocol data units, which have

It is indeed possible to check for source and/or destination MAC
address for STP packets.
Thanks a lot, Jan. My guess is that a certain vendor is using netfilter
"underneath", so I was trying to figure out why their firewalls had the
ability to filter based on source MAC, but not destination. So I've no
idea.
Have a pleasant day.
