The purpose of this new packet type is to allow to forward an IP multicast packet with less transmissions / overhead than the multicast-via-multiple-unicasts approach. Or to reach a lot more destinations (currently up to 196, depending on the payload size, see Wiki documentation for details) than with the default multicast fanout for the via-unicasts approach.
Please don't forget that batctl's tcpdump+wireshark also requires support for parsing it. Most likely, this was not added yet to not confuse third parties in case the packet format changes.
I have now acked the various patches and have queued them up for submission to net-next. But it would be good when Simon also checks them.
And we must also first release 2023.2 (including submission for net + net-next) before these patches can be added to the batman-adv repository.
Kind regards, Sven
