17.3. RTEMS Legacy Network Stack

This document describes the RTEMS specific parts of the legacy FreeBSD TCP/IP stack. The stack is based on a old version of the FreeBSD network stack. A lot of RTEMS specific changes have been added and there is no realistic chance to ever update it to a newer FreeBSD version. There will be no further development of this stack. If you start with a new target, please select one of the other network stacks that support RTEMS.
