Avid Feroceon-KW
Avid devices including the Feroceon-KW embedded Linux controller include: - Avid E3 Engine - Avid Stage 16
This Feroceon-KW controller appears to be for the network switch that controls the three AVB Ethernet ports (ports A, B, and C). 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.

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

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.
- Networking
This device can only be reached by first connecting to the Avid Diamond Platform controller of the Avid E3 Engine, 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 Avid S3 Console to function as a controller for the Avid E3 engine.
