Thanks for the quick turnaround Mirja. I'll add text that refers to the Reserved field in the the next rev. Thanks, Fabio On 1/8/20, 2:22 AM, "Mirja Kuehlewind" <ietf@kuehlewind.net> wrote: Hi Fabio, Thanks for all the work. Changes look good to me and I think my discuss comments are addressed. One small comment/nit: I think you also should define the “Reserved” field in Figure 2. It’s not mention in the text, and even though the meaning is obvious, I assume it was an oversight that it's not described. Given the large set of changes, it’s good that another wg last call took place. I think given more or less whole document has changes, it could be approbate to also have another IETF last call and put it back on a future telechat agenda. But I let Deborah decide about this.
