Re: [aqm] Who supports tsvwg adoption of adding ECN to L2 or tunnel protocols?

I look through the whole document and I really think it's a good idea to propagate congestion signals through different networks,
it will be good to deal with the congestion situation especially when there are lower layer en route.
