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
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).

Davicom DM9601 data sheet,
The udav device driver first appeared in OpenBSD 3.7.
The udav driver was written by Shingo WATANABE <firstname.lastname@example.org> and
ported to OpenBSD by Jonathan Gray <email@example.com>.
RD9700 support by Takayoshi SASANO <firstname.lastname@example.org>.
The RD9700 sometimes lacks zero-length packets to terminate USB trancac-
tions, which can cause USB IOERRORs.
