DESCRIPTION
The pcn device driver supports Ethernet interfaces based on the AMD
PCnet-PCI family of Ethernet chips. The chips supported by the pcn
driver include:
o Am79c970 PCnet-PCI Single-Chip Ethernet Controller for PCI Local Bus
o Am79c970A PCnet-PCI II Single-Chip Full-Duplex Ethernet Controller
for PCI Local Bus
o Am79c971 PCnet-FAST Single-Chip Full-Duplex 10/100Mbps Ethernet
Controller for PCI Local Bus
o Am79c972 PCnet-FAST+ Enhanced 10/100Mbps PCI Ethernet Controller with
OnNow Support
o Am79c973/Am79c975 PCnet-FAST III Single-Chip 10/100Mbps PCI Ethernet
Controller with Integrated PHY
PCnet-PCI chips are found on some Hewlett-Packard PCI Ethernet boards,
and on the Allied Telesyn AT-2700TX PCI Ethernet board. They are also
found on some processor evaluation boards as an example peripheral.
The pcn driver also supports the emulated PCnet-PCI interface provided by
VMware.
