NAME

     ex - driver for 3Com Fast EtherLink XL (3c900, 3c905, 3c980) and similar
     PCI bus and cardbus Ethernet interfaces


SYNOPSIS

     ex* at cardbus? dev ? function ?
     ex* at pci? dev ? function ?


DESCRIPTION

     3Com Ethernet and Fast Ethernet cards supported by the ex driver include:

     3c450-TX 10/100 Ethernet
     3c555 MiniPCI 10/100 Ethernet
     3c556 MiniPCI 10/100 Ethernet
     3c556B MiniPCI 10/100 Ethernet
     3c575-TX Ethernet
     3c575B-TX Ethernet
     3c575CT Ethernet
     3c900-TPO Ethernet
     3c900-COMBO Ethernet
     3c900B-TPC Ethernet
     3c900B-TPO Ethernet
     3c900B-COMBO Ethernet
     3c905-T4 10/100 Ethernet
     3c905-TX 10/100 Ethernet
     3c905B-COMBO 10/100 Ethernet
     3c905B-FX 10/100 Ethernet
     3c905B-T4 10/100 Ethernet
     3c905B-TX 10/100 Ethernet
     3c980 Server Adapter 10/100 Ethernet
     3c980C-TXM 10/100 Ethernet
     3cSOHO100-TX 10/100 Ethernet

     All versions of the Etherlink XL (except the older 3c900 and 3c905) sup-
     port IPv4/TCP/UDP checksumming in hardware.  The ex driver supports this
     feature of the chip.  See ifconfig(8) for information on how to enable
     this feature.


MEDIA SELECTION

     See ifmedia(4).
