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:
- 
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 Controller for PCI Local Bus
- 
Am79c972 PCnet-FAST+ Enhanced 10/100Mbps PCI Ethernet Controller with OnNow Support
- 
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.
 
HISTORY
 The pcn driver first appeared in NetBSD 1.6.
