NAME
     ure -- RealTek RTL8152/RTL8153 USB to Ethernet controller driver

SYNOPSIS
     To compile this driver into the kernel, place the following lines in your
     kernel configuration file:

	   device uhci
	   device ohci
	   device usb
	   device miibus
	   device uether
	   device ure

     Alternatively, to load the driver as a module at boot time, place the
     following line in loader.conf(5):

	   if_ure_load="YES"

DESCRIPTION
     The  ure driver provides support for USB Ethernet adapters based on the Re-
     alTek 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).

DIAGNOSTICS
     ure%d: watchdog timeout  A packet was queued for transmission and a  trans-
     mit command was issued, however the device failed to acknowledge the trans-
     mission before a timeout expired.
