PCN(4)                       Device Drivers Manual                      PCN(4)

     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
     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

     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
