NAME

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

SYNOPSIS

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

DESCRIPTION

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

All versions of the EtherLink XL (except the older 3c900 and 3c905) support 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

Some of these network interfaces support the Media Independent Interface (MII), a bus which can have at least one arbitrary Physical interface (PHY) chip on it. NetBSD supports MII and has separate drivers for many different PHY chips, including ukphy(4), a generic PHY driver that can support many PHY chips that NetBSD does not yet have a specific driver for.

Support for the PHY found on a given NIC must be configured into a NetBSD kernel config(1) for this driver to work properly in those cases.

See ifmedia(4), and mii(4).
