axe — ASIX Electronics AX88x7x/760 USB Ethernet driver

Authors

       The axe driver was written by Bill Paul <wpaul@windriver.com>.

Debian                                          November 24, 2015                                         AXE(4)

Description

       The axe driver provides support for USB Ethernet adapters based on the ASIX Electronics AX88172, AX88178,
       AX88772, AX88772A, AX88772B and AX88760 USB 2.0 chipsets.

       The AX88172, AX88772, AX88772A, AX88772B and AX88760 contain a 10/100 Ethernet MAC with MII interface and
       are designed to work with both Ethernet and HomePNA transceivers.  The AX88178 has a 10/100/1000 Ethernet
       MAC with GMII/RGMII interface for interfacing with Gigabit Ethernet PHY.

       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 rc.conf(5).

       10baseT/UTP  Set  10Mbps  operation.   The  ifconfig(8) mediaopt option can also be used to select either
                    full-duplex or half-duplex modes.

       100baseTX    Set 100Mbps (Fast Ethernet) operation.  The ifconfig(8) mediaopt option can also be used  to
                    select either full-duplex or half-duplex modes.

       1000baseT    Set  1000Mbps  (Gigabit Ethernet) operation (AX88178 only).  The ifconfig(8) mediaopt option
                    can also be used to select either full-duplex or half-duplex modes.

       The axe driver supports the following media options:

       full-duplex  Force full duplex operation.

       half-duplex  Force half duplex operation.

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

Diagnostics

axe%d:watchdogtimeout  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:nomemoryforrxlist  The driver failed to allocate an mbuf for the receiver ring.
