This version implements the support for Multipath TCP.

It affects the way TCP is handled by adding a packet type for TCP options.  It

also adds a packet type MPTCP as subtype of a TCP option (see

scapy/layers/mptcp.py for details).

You can use the script "launcher" to start scapy with the modified script. It

works only if you are in the same directory that the python "scapy" module.

EXAMPLE RUN

$ ./laucher
