Thank you for the patches!

Unfortunately, I don't think it would be wise to accept them now: for 
the moment, these suboptions are ignored at the reception. If we accept 
them and change some variables like you did, we would need to make sure 
the kernel is still acting correctly. In other words, we would need tests:
* For MP_PRIO, there are still quite some works to do regarding the 
scheduling of the packets between the different MPTCP subflows to do 
before supporting this.
* For MP_FAIL, we should forward the info to the path manager.
* For MP_FASTCLOSE, we should close connections and ACK this.

Also, net-next is closed for the moment: 
http://vger.kernel.org/~davem/net-next.html

I would suggest you to discuss about that on MPTCP mailing list. We also 
have meetings every Thursday. New devs are always welcome to contribute 
to new features and bug-fixes!

Cheers,
Matt
