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.
