Re: [Gen-art] [6tisch] Genart last call review of draft-ietf-6tisch-msf-10

Dear Tengfei: Thank you for getting back to me and your time to address my
review.

The paragraph you suggest is very much improved, with one small change that
will make it even better, as described next.

In the last sentence of your proposed change, s/The algorithm of limiting
the/However, any such algorithm of limiting the/

Once again, thanks.
