NAME

     kue — Kawasaki LSI KL5KUSB101B USB Ethernet 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 kue

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

           if_kue_load="YES"

DESCRIPTION

     The kue driver provides support for USB Ethernet adapters based on the Kawasaki LSI
     KL5KLUSB101B chipset.

     The KL5KLUSB101B supports a 128-entry multicast filter, single perfect filter entry for the
     station address and promiscuous mode.  Packets are received and transmitted over separate
     USB bulk transfer endpoints.

     The Kawasaki chipset supports only 10Mbps half-duplex mode, hence there are no ifmedia(4)
     modes to select.

     For more information on configuring this device, see ifconfig(8).

DIAGNOSTICS

     kue%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.

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

BUGS

     The kue driver does not accumulate Ethernet collisions statistics because the Kawasaki
     firmware does not appear to maintain any internal statistics.
