AXE(4)		       FreeBSD Kernel Interfaces Manual			AXE(4)

     axe -- ASIX Electronics AX88x7x/760 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 uether
	   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,	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	Ether-
     net 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 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 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

     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).

     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.
