T_XPatchset v2 is out for the Linux bridge, to reduce checks in the #multicast fast path, and to later propagate a safety multicast (in)active state to #switchdev/#DSA:
https://patchwork.kernel.org/project/netdevbpf/cover/20260206030123.5430-1-linus.luessing@c0d3.blue/
Includes some fixes and got some nice Linux selftests: https://patchwork.kernel.org/project/netdevbpf/patch/20260206030123.5430-3-linus.luessing@c0d3.blue/
This is also the version currently used in this OpenWrt draft PR for #realtek / #rtl83xx (v6 - v8): https://github.com/openwrt/openwrt/pull/18780
AskUbuntu
v8 for the #multicast patchset for the #OpenWrt #Realtek target pushed: https://github.com/openwrt/openwrt/pull/18780#issuecomment-3808673943
Now rebased onto the v6.18 PR for #OpenWrt. And with many style changes, which were suggested in the comments of this PR.
Curiously without needing to cherry-pick the mdio_aux reset-gpio revert to fix https://github.com/openwrt/openwrt/issues/18620. Worked out-of-the-box on v6.18. Will need to dig deeper later what in OpenWrt or between 6.12->6.18 might have fixed that.

Finally got a v6, of a #multicast PR for #OpenWrt for the #Realtek / #rtl83xx target out: https://github.com/openwrt/openwrt/pull/18780
The whole thing, especially for the Linux bridge + DSA got bigger than expected (from ~4 patches to now 16...). But djfe was so kind to help with rebasing to 6.12 on OpenWrt. Then also got stuck on a regression in OpenWrt, but @cuechan's impartial view and technical expertise helped with that.
Next will need to circle back to upstream Linux for a new submission (after some sleep...)

@c8h4 @dragonarchitect @demicus well, I've not encountered problems with #Ethernet.
- OFC some folks will not understand that cheap #Realtek, #Mediatek, #Aquantia & #ASIX-NICs don't do #PacketFiltering and -Sorting in hardware thus never saturating the physical link width and also causing excessive CPU load compared to some #Intel or #Mellanox NICs, but that's jist the nature of it.
The biggest problems I had were garbage NICs from #Broadcom under #BSDs: These are just horrendously bad!
