AXE(4)			 BSD Kernel Interfaces Manual			AXE(4)

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

     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):


     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 Ether-
     net 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 end-

     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 spec-
		  ifying 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).

     The axe driver supports ASIX Electronics AX88172/AX88178/AX88772 based
     USB Ethernet adapters including:

     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.

     The axe device driver first appeared in FreeBSD 5.0.

     The axe driver was	written	by Bill	Paul <>.
