pcn -- AMD PCnet-PCI Ethernet family driver
pcn* at pci? dev ? function ?
Configuration of PHYs may also be necessary. See mii(4).
The pcn device driver supports Ethernet interfaces based on the AMD
PCnet-PCI family of Ethernet chips. The chips supported by the pcn
· Am79c970 PCnet-PCI Single-Chip Ethernet Controller for PCI Local Bus
· Am79c970A PCnet-PCI II Single-Chip Full-Duplex Ethernet Controller
for PCI Local Bus
· Am79c971 PCnet-FAST Single-Chip Full-Duplex 10/100Mbps Ethernet Con-
troller for PCI Local Bus
· Am79c972 PCnet-FAST+ Enhanced 10/100Mbps PCI Ethernet Controller with
· 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
arp(4), ifmedia(4), mii(4), netintro(4), pci(4), ifconfig(8)
The pcn driver first appeared in NetBSD 1.6.
The pcn driver was written by Jason R. Thorpe
