Subject: Proposal: Interop matrix letter for preferred address

Hello,

A few hours ago, Christian Huitema pointed out to me that the "M"
letter in the 20th Implementation Draft [1] only covers usage of
server CIDs by the client.  (I thought that it meant "migration to
server's preferred address is successful.")

We should have a dedicated letter for this.  I propose:

    F:  Success if server specifies a preferred address in its
        transport parameters and the client migrates to it.

  - Dmitri.
