8101 Datasheet, PDF (18/172 Pages) LSI Computer Systems – Gigabit Ethernet Controller

internal 16-bit registers that can be accessed through the register
interface. These registers contain configuration inputs, status outputs,
and management counter results.
The 8101/8104 is ideal as an Ethernet controller for Gigabit Ethernet
switch ports, uplinks, backbones, and adapter cards.
