/**
* \defgroup uipsplit uIP TCP throughput booster hack
* @{
*
* The basic uIP TCP implementation only allows each TCP connection to
* have a single TCP segment in flight at any given time. Because of
* the delayed ACK algorithm employed by most TCP receivers, uIP's
* limit on the amount of in-flight TCP segments seriously reduces the
* maximum achievable throughput for sending data from uIP.
*
* The uip-split module is a hack which tries to remedy this
* situation. By splitting maximum sized outgoing TCP segments into
* two, the delayed ACK algorithm is not invoked at TCP
* receivers. This improves the throughput when sending data from uIP
* by orders of magnitude.
*
* The uip-split module uses the uip-fw module (uIP IP packet
* forwarding) for sending packets. Therefore, the uip-fw module must
* be set up with the appropriate network interfaces for this module
* to work.
