DESCRIPTION
The ure driver provides support for USB Ethernet adapters based on the
RealTek RTL8152, RTL8153/RTL8153B, and RTL8156/RTL8156B USB Ethernet
controllers, as well as USB Ethernet PHYs provided by rgephy(4).
NICs based on the RTL8152 are capable of 10 and 100Mbps. NICs based on
the RTL8153 or provided by rgephy(4) are capable of 10, 100, and
1000Mbps. NICs based on the RTL8156 are capable of 10, 100, 1000, and
2500Mbps 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 (Gigabit Ethernet) operation over twisted
pair. The RealTek gigE chips support 1000Mbps in
full-duplex mode only.
2500base-T Set 2500Base-T operation over twisted pair. The RealTek
8156/8156B chips support 2500Mbps in full-duplex mode only.
The ure driver supports the following media options for 10/100 operation:
full-duplex Force full-duplex operation.
half-duplex Force half-duplex operation.
