DESCRIPTION

     The axen driver provides support for USB Ethernet adapters based on the
     ASIX Electronics AX88178a and AX88779 USB 2.0 chipsets (potentially the
     AX88779 supports USB 3.0, but there is currently no xhci support in
     NetBSD), including the following:

           Kurotoshiko GbE-USB3.0
           Logitec LAN-GTJU3
           Shanghai Donya DN-84327

     The axen driver supports the following media types:

     autoselect  Enable autoselection of the media type and options (this is
                 the default).  The user can manually override the autose-
                 lected mode by adding media options to the appropriate
                 ifconfig.if(5) file.

     10baseT     Set 10Mbps operation.

     100baseTX   Set 100Mbps (Fast Ethernet) operation.

     1000baseT   Set 1000Mbps (Gigabit Ethernet) operation.

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