MPTCP wVegas congestion control by Enhuan Dong

Enable/disable MPTCP through the socket-API: You can explicitly disable MPTCP by setting the TCP-socket option "MPTCP_ENABLED" to 0. By default, MPTCP is always enabled. If however, you set the sysctl mptcp_enabled to 2, then, MPTCP is by default disabled and it can be used by setting the socket-option to 1. Keep in mind, that you must set the socket-option before calling "connect" or "listen" on the socket.
