RUE(4)                 FreeBSD Kernel Interfaces Manual                 RUE(4)

NAME
     rue -- RealTek RTL8150 USB To Fast Ethernet controller driver

SYNOPSIS
     device uhci
     device ohci
     device usb
     device miibus
     device rue

DESCRIPTION
     The rue driver provides support for USB Ethernet adapters based on the
     RealTek RTL8150 USB to Fast Ethernet controller chip.  This includes the
     Melco Inc. LUA-KTX and the GREEN HOUSE GH-USB100B.

     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 rue 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 rue 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
     rue%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.

     rue%d: rx list init failed  The driver failed to allocate an mbuf for the
     transmitter ring.

     rue%d: no memory for rx list  The driver failed to allocate an mbuf for
     the receiver ring.
