NAME

     axe - ASIX Electronics AX88172/178/772 USB Ethernet driver

SYNOPSIS

     To compile this driver into the kernel, place the following lines in your
     kernel configuration file:

           device ehci
           device uhci
           device ohci
           device usb
           device miibus
           device axe

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

           if_axe_load="YES"

DESCRIPTION

     The axe driver provides support for USB Ethernet adapters based on the
     ASIX Electronics AX88172, AX88178 and AX88772 USB 2.0 chipsets.

     The AX88172 and AX88178 are USB 2.0 devices that contain a 10/100
     Ethernet MAC with MII interface and are designed to work with both
     Ethernet and HomePNA transceivers.  The AX88772 will additionally support
     10/100/1000 MACs.

     These devices will operate with both USB 1.x and USB 2.0 controllers,
     however performance with 1.x controllers will be limited since the USB
     1.x standard specifies a maximum transfer speed of 12Mbps.  Users with
     USB 1.x controllers should therefore not expect to actually achieve
     100Mbps speeds with these devices.

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

     The axe 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 axe 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

     axe%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.

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