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 as-
     sign 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 transac-
     tions, which can cause USB	IOERRORs.
