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).
