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
-

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).

The
udav device driver first appeared in
OpenBSD 3.7.
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>.
The RD9700 sometimes lacks zero-length packets to terminate USB transactions,
which can cause USB IOERRORs.
