* - TX data is marked as 'sent' (i.e. acknowledged; sent callback is called) right

This directory contains a script ('makefsdata') to create C code suitable for
httpd for given html pages (or other files) in a directory.
There is also a plain C console application doing the same and extended a bit.
Usage: htmlgen [targetdir] [-s] [-i]s
targetdir: relative or absolute path to files to convert
switch -s: toggle processing of subdirectories (default is on)
switch -e: exclude HTTP header from file (header is created at runtime, default is on)
switch -11: include HTTP 1.1 header (1.0 is default)
if targetdir not specified, makefsdata will attempt to
process files in subdirectory 'fs'.

/**

*
* This is a simple performance measuring client/server to check your bandwith using
* iPerf2 on a PC as server/client.
* It is currently a minimal implementation providing a TCP client/server only.
*
* @todo:
* - implement UDP mode
* - protect combined sessions handling (via 'related_master_state') against reallocation
* (this is a pointer address, currently, so if the same memory is allocated again,
* session pairs (tx/rx) can be confused on reallocation)
