Re: [dhcwg] DHCP Options for Network-Assisted Multipath TCP (MPTCP)

[Dan Seibel <[e-mail]>]

I think your document gives a good overall impression of how this will
work (having no experience with MPTCP implementations I found this fairly
easy to follow).

A few questions:

- in sections 4.2 you mention a client requests this option, but does it
have to?  I.e could a server send this option without the client
requesting it, and the client would still accept it? (should there be a
MUST or SHOULD statement in there?)

- similarly, in section 5 I don¹t see any mention of if the server needs
to see a request for this option to hand it out.
