NAME

     cue — CATC USB-EL1210A 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 cue

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

           if_cue_load="YES"

DESCRIPTION

     The cue driver provides support for USB Ethernet adapters based on the Computer Access
     Technology Corporation's USB-EL1210A chipset.

     The USB-EL1210A supports a 512-bit multicast hash filter, single perfect filter entry for
     the station address and promiscuous mode.  Packets are received and transmitted over
     separate USB bulk transfer endpoints.

     The CATC 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).

HARDWARE

     The cue driver supports CATC USB-EL1210A based USB Ethernet adapters including:

     ·   Belkin F5U011/F5U111
     ·   CATC Netmate
     ·   CATC Netmate II
     ·   SmartBridges SmartLink

DIAGNOSTICS

     cue%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.

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