Hi Yuhan I am a bit familiar with this change as we tried it in out POC [1] for IPv6 dual-stack. It achieves a similar function, as best as I understand, by allowing multiple external bridges (and, therefore, external interfaces). The feature I am providing here achieves approximately the same thing (explicitly, a dual-stack arrangement) on the *same* interface, thereby requiring only a *single* external bridge (and *single* external interface).
I think it just gives more flexibility. We can surely discuss. Thanks for your comments!! Good discussion.
