Re: [Roll] Last Call: <draft-ietf-roll-trickle-mcast-06.txt> (Multicast Protocol for Low power and Lossy Networks (MPL)) to Proposed Standard

Hi Axel,

Some slight rolling of eyes as this I-D has been through plenty of reviews and
last calls, but in the end we appreciate all review comments however and
whenever.

Hoping the authors will generate an answer for you soon.

Thanks,
Adrian
