Multipath TCP for FreeBSD v0.4

[Nigel Williams]

Hi,

We recently released a new tech report "Design Overview of Multipath TCP 
version 0.4 for FreeBSD-11" [1]. The report provides some details on 
various aspects of the implementation (session management, data-level 
retransmission etc), as of the most recent v0.4 patch [2].

cheers,
nigel
