Wait.

May this break local multicast listener that are bound to the bridge
interface? Assuming the bridge interface got an IP address, and that
there is local multicast listener.

Missing anything here?

Hm, for multicast packets usually the code path a few lines
later in br_handle_frame_finish() should be taken instead.

But you might be right for IP multicast packets with a unicast MAC
destination (due to whatever reason, for instance via DNAT'ing
again).

Will check that - thanks!
