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.
Xenomai RTNet
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.
