DESCRIPTION

The ure driver provides support for USB Ethernet adapters based on the RealTek RealTek RTL8152 and RTL8153 USB Ethernet controllers.

NICs based on the RTL8152 are capable of 10 and 100Mbps speeds. NICs based on the RTL8153 are capable of 10, 100 and 1000Mbps operation.

The ure driver supports the following media types:

autoselect

Enable auto selection of the media type and options. The user can manually override the auto selected mode by adding media options to the /etc/rc.conf file.

10baseT/UTP

Set 10Mbps operation. The mediaopt option can also be used to select either full-duplex or half-duplex modes.

100baseTX

Set 100Mbps (Fast Ethernet) operation. The mediaopt option can also be used to select either full-duplex or half-duplex modes.

1000baseTX

Set 1000baseTX operation over twisted pair. The RealTek gigE chips support 1000Mbps in full-duplex mode only.

The ure driver supports the following media options:

full-duplex

Force full duplex operation.

half-duplex

Force half duplex operation.

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