Ethernet
All physical aspects of the 100BASE-TX Ethernet are managed by the base system which takes care of things like low-level initialization and power management of the hardware. The logical aspect of the 100BASE-TX Ethernet interface is exposed as a regular network interface to the user system.
The Ethernet interface is by default configured with the static IP 198.18.4.2
,
but it can also be changed to use DHCP.
The Ethernet service is used to handle the Ethernet interfaces.
