UDAV(4)                  BSD Kernel Interfaces Manual                  UDAV(4)

NAME
     udav -- Davicom DM9601 10/100 USB Ethernet device

SYNOPSIS
     udav*  at uhub?
     amphy* at mii?

DESCRIPTION
     The udav driver provides support for USB Ethernet adapters based on the
     Davicom DM9601 USB-ether bridge chip.

     The udav driver supports the following adapters:

           Corega FEther USB-TXC
           HenTong WK-668
           Konig CMP-NWUSB10
           ShanTou ST268
           ShanTou ZT6688
           ShanTou ADM8515

     The udav driver also supports CoreChip RD9700.  As many of these units
     ship with the same MAC address, it is highly recommended to use
     ifconfig(8) lladdr to set the address manually, or lladdr random to
     assign a random address.

     For more information on configuring this device, see ifconfig(8).

HISTORY
     The udav device driver first appeared in OpenBSD 3.7.

AUTHORS
     The udav driver was written by Shingo WATANABE <nabe@nabechan.org> and
     ported to OpenBSD by Jonathan Gray <jsg@openbsd.org>.

     RD9700 support by Takayoshi SASANO <uaa@uaa.org.uk>.

BUGS
     The RD9700 sometimes lacks zero-length packets to terminate USB trancac-
     tions, which can cause USB IOERRORs.
