[DNA] Issue 1: Remove the second part of Abstract

Dear DNA WG

This is an attempt to resolve this issue:

Issue 1
Jim Bound proposed to remove the second part of Abstract.
* This may necessitate the rewriting of Abstract.

Suggested resolution: We rephrased the Abstract as belows.

Abstract

At the time a host establishes a new link-layer connection, it may or
may not have a valid IP configuration for Internet connectivity. The
host may check for link change, i.e. determine whether a link change
has occurred, and then, based on the result, it can automatically
decide whether its IP configuration is still valid or not. During
link identity detection, the host may also collect necessary information
to initiate a new IP configuration for the case that the IP subnet has
changed. In this memo, this procedure is called Detecting Network
Attachment (DNA). DNA schemes should be 1) precise, 2) sufficiently
fast and 3) of limited signaling.

Please register your opinion if you have any comments, otherwise

we'll update the goals draft accordingly and move it forward.

Thanks for Greg's kind work, we now have the issue list at
