Richard:

Maybe you should read the draft.

I removed all references to my proposal of how to use the Flow label for RPL.

What the 6MAN draft is now asking is only the right to manipulate a flow label in the LLN, RPL or not RPL, be it only to reset it to zero so as to elide it.

The Idea to propose a 6lowpan compression is actually from Laurent and I was the first on the ML to support it.

Cheers,
Pascal
