ex
— driver for
3Com Fast EtherLink XL (3c900, 3c905, 3c980) and similar PCI bus and cardbus
Ethernet interfaces
ex* at cardbus? function ?
ex* at pci? dev ? function ?
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.
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).
