.Sh NAME
.Nm ure
.Nd "RealTek RTL8152/RTL8153 USB to Ethernet controller driver"
.Sh SYNOPSIS
To compile this driver into the kernel,
place the following lines in your
kernel configuration file:
.Bd -ragged -offset indent
.Cd "device uhci"
.Cd "device ohci"
.Cd "device usb"
.Cd "device miibus"
.Cd "device uether"
.Cd "device ure"
.Ed
.Pp
Alternatively, to load the driver as a
module at boot time, place the following line in
.Xr loader.conf 5 :
.Bd -literal -offset indent
if_ure_load="YES"
.Ed
.Sh DESCRIPTION
The
.Nm
driver provides support for USB Ethernet adapters based on the RealTek
RealTek RTL8152 and RTL8153 USB Ethernet controllers.
.Pp
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.
.Pp
The
.Nm
driver supports the following media types:
.Bl -tag -width ".Cm 10baseT/UTP"
.It Cm 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
.Pa /etc/rc.conf
file.
.It Cm 10baseT/UTP
Set 10Mbps operation.
The
.Cm mediaopt
option can also be used to select either
.Cm full-duplex
or
.Cm half-duplex
modes.
.It Cm 100baseTX
Set 100Mbps (Fast Ethernet) operation.
The
.Cm mediaopt
option can also be used to select either
.Cm full-duplex
or
.Cm half-duplex
modes.
.It Cm 1000baseTX
Set 1000baseTX operation over twisted pair.
The RealTek gigE chips support 1000Mbps in
.Cm full-duplex
mode only.
.El
.Pp
The
.Nm
driver supports the following media options:
.Bl -tag -width ".Cm full-duplex"
.It Cm full-duplex
Force full duplex operation.
.It Cm half-duplex
Force half duplex operation.
