/**
* @addtogroup internal_multiplexer Internal Multiplexer module
*
* The Internal Multiplexer is the link between the virtual tun/tap
* network interface and the \link data_control Data Channel Control
* module\endlink. It reads packets from the virtual network interface,
* determines for which remote OpenVPN peer they are destined, and then
* passes the packets on to the Data Channel Control module together with
* information about their destination VPN tunnel instance.
*
* This module also handles packets traveling in the reverse direction,
* which have already been processed by the Data Channel Control module
* and are destined for a locally reachable host.
