The vendor driver lists a bunch of possible tables: [1]
I'll leave any effort for multicast out for now... it's not the main
use-case I am looking at right now.

Most of these tables are needed because the switch HW can do layer 3 
(IP) multicast handling. I think normally Linux takes care of this with 
DSA drivers and we only tell the switch where to forward based on MAC 
addresses.

As always: thank you for your amazing explanations, hints and pointers!
Also I would like to point out that I am still doing all of this in my
spare time. Whenever you have other conversations to focus on: please
do so! For me it's not critical if you're getting back to me a few
days sooner or later.


Best regards,
Martin
