General Information

Xenomai uses the RTNet stack to provide real-time Ethernet. RTNet provides deterministic versions of various protocols (UDP/IP, IMCP, ARP). Xenomai provides several real-time Ethernet drivers, the stack, and various tools. This document explains how to load a real-time Ethernet driver and perform basic tests. The links below will help augment this information as well as discuss programming using the RTnet stack.

As with the other real-time drivers, the Linux driver must be detached the interface before loading that real-time driver.

For example on IMX6 target the fec device must be unbound from the Linux driver and attached to the real-time driver.
