NAME
rue
- RealTek RTL8150 USB to Fast Ethernet controller driver
SYNOPSIS
To compile this driver into the kernel,
place the following lines in your
kernel configuration file:
device uhcidevice ohcidevice usbdevice miibusdevice rue
Alternatively, to load the driver as a
module at boot time, place the following line in
loader.conf5:
if_rue_load="YES"
DESCRIPTION
The
driver provides support for USB Ethernet adapters based on the RealTek
RTL8150 USB to Fast Ethernet controller chip.
The RTL8150 contains an integrated Fast Ethernet MAC, which supports
both 10 and 100Mbps speeds in either full or half duplex.
Although designed to interface with
100Mbps peripheral, the existing USB standard specifies a maximum
transfer speed of 12Mbps.
Users should therefore not expect to actually
achieve 100Mbps speeds with this device.
The
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.
The
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).
