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).
