2.3.8.2 Intel 82559
The Ethernet interface is based on an Intel 82559 Ethernet controller that supports both
10BASE-T and 100BASE-TX. The 82559 consists of both the Media Access Controller
(MAC) and the physical layer (PHY) interface combined into a single component solution.
The 32-bit PCI controller provides enhanced scatter-gather bus mastering capabilities and
enables the 82559 to perform high speed data transfers over the PCI bus. Its bus master
capabilities enable the component to process high level commands and perform multiple
operations, which lowers CPU utilization by off-loading communication tasks from the CPU.
Two large transmit and receive FIFOs of 3 Kbytes each help prevent data under runs and
overruns while waiting for bus accesses. This enables the 82559 to transmit data with
minimum interframe spacing (IFS).
