 The Multipath TCP Daemon Library is a library to build plugins for the
 mptcpd, short for Multipath TCP Daemon. This library can be used to
 perform Multipath TCP path management related operations in the user

 The daemon interacts with the Linux kernel through a generic Netlink
 connection to track per-connection information (e.g. available remote
 addresses), available network interfaces, request new MPTCP subflows,
 handle requests for subflows, etc. The plugin can react on events and
 requests path management related operations to create subflows,
 advertise addresses, etc.
