NAME

     aue — ADMtek AN986 Pegasus 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 miibus
           device uether
           device aue

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

           if_aue_load="YES"

DESCRIPTION

     The aue driver provides support for USB Ethernet adapters based on the ADMtek AN986 Pegasus
     chipset.

     The LinkSys USB10T adapters that contain the AN986 Pegasus chipset will operate at 100Base-
     TX and full-duplex.

     The Pegasus contains a 10/100 Ethernet MAC with MII interface and is designed to work with
     both Ethernet and HomePNA transceivers.  Although designed to interface with 100Mbps
     peripherals, the existing USB standard specifies a maximum transfer speed of 12Mbps.  Users
     should therefore not expect to actually achieve 100Mbps speeds with these devices.

     The Pegasus supports a 64-bit multicast hash table, single perfect filter entry for the
     station address and promiscuous mode.  Packets are received and transmitted over separate
     USB bulk transfer endpoints.

     The aue driver supports the following media types:

     autoselect            Enable autoselection of the media type and options.  The user can
                           manually override the autoselected mode by adding media options to the
                           /etc/rc.conf file.

     10baseT/UTP           Set 10Mbps operation.  The mediaopt option can also be used to enable
                           full-duplex operation.  Not specifying full duplex implies half-duplex
                           mode.

     100baseTX             Set 100Mbps (Fast Ethernet) operation.  The mediaopt option can also
                           be used to enable full-duplex operation.  Not specifying full duplex
                           implies half-duplex mode.

     The aue driver supports the following media options:

     full-duplex           Force full duplex operation.  The interface will operate in half
                           duplex mode if this media option is not specified.

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

DIAGNOSTICS

     aue%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.

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