  1. Avid / E3 Engine / Feroceon-KW

This controller appears to be for the network switch that controls the three AVB Ethernet ports. This assumption is made based on the active switchd2 and kirkwoodfw daemons that are running, which are for the Kirkwood AVB ethernet switch chipset that are produced by Marvell.

[ARM926EJ-S Technical Reference Manual](http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0198e/Cacheeja.html)

It looks like I can compile Go code for the device. https://groups.google.com/forum/#!topic/golang-nuts/dkzGY-4OgJw

    1. Overview
      1. Hardware

- Processor: ARM926EJ-S rev 1 (v5l) - BogoMIPS: 792.57 - Hardware: Feroceon-KW (Kirkwood?) - RAM: 256M

      1. Operating system

The OS is Linux, and is a custom distribution. On the S3L-X 4.6.1.4 release this OS version is 0.8.9.35.

      1. Networking

This device can only be reached via the E3 Engine, and not directly.

This controller provides three network interfaces, eth0 and eth0:avahi (a virtual interface managed by avahi-daemon) and eth1. eth0 is physically connected to the Ethernet ports.

The eth0:avahi interface has a [link-local address](https://en.wikipedia.org/wiki/Link-local_address) that is available even though the eth0 interface, and is accessible using the address Core6420B9.local.

The Ethernet driver is [sk98lin](http://man7.org/linux/man-pages/man4/sk98lin.4.html) (`/sys/bus/pci/drivers/sk98lin`), which is an obsolete driver for the Marvell/SysKonnect Gigabit chipset that was removed from the Linux kernel in version 2.6.26.

The kirkwoodfw daemon has references to EuCon in the binary, which indicates it handles the EUCON protocol, which enables the S3 Console to function as a controller for the E3 engine.
