Re: [multipathtcp] I-D Action: draft-ietf-mptcp-rfc6824bis-11.txt

Hi all,

This update to rfc6824bis acts upon the feedback from IETF101 in London.

Specifically:

- Remove the Experimental option specification on request of Olivier (but keeping the option type reserved);
- Move TFO discussion to the Appendix since this is an Experimental specification;
- Add some clarification text regarding processing unexpected ACK numbers (which came out of the TFO discussion).

Regards,
Alan
