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.
