NAME

     ure — RealTek RTL8152 USB to Fast 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 RealTek RTL8152 USB
     to Fast Ethernet controller chip.

     The RTL8152 contains an integrated Fast Ethernet MAC, which supports both 10 and 100Mbps
     speeds in either full or half duplex.

     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.

     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 transmit command was
     issued, however the device failed to acknowledge the transmission before a timeout expired.
