Patchset 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
Use #BSD for good networking, nuff said... Use #OPNsense for a firewall/router, nuff said...
Me trying to use #multicast snooping with this in our hackspace: After several hours of debugging, realizing it's not bc. of the #OpenWrt powered, #rtl83xx based switch I've added, nor the new patches I've made and added to it. But because of this two years old, ignored #OPNsense (or #FreeBSD?) bug with #MLD: https://github.com/opnsense/core/issues/6247
