     The AX88172, AX88178, and AX88772 are USB 2.0 devices designed to work
     with either Ethernet or HomePNA transceivers.  The AX8172 and AX88772
     contain 10/100 Ethernet MACs with MII interfaces.	The AX8178 contains a
     10/100/1000 Gigabit Ethernet MAC with a GMII/MII interface.  All adapters
     will operate with either USB 1.x or 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.

     A 64-bit multicast hash table is supported, single perfect filter entry
     for the station address, all-multicast mode, and promiscuous mode.
     Packets are received and transmitted over separate USB bulk transfer

     The axe 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
		 autoselected mode by adding media options to the appropriate
		 hostname.if(5) file.

     10baseT	 Set 10Mbps operation.

     100baseTX	 Set 100Mbps (Fast Ethernet) operation.

     1000baseT	 Set 1000Mbps (Gigabit Ethernet) operation (AX88178 only).

     The axe driver supports the following media options:

     full-duplex  Force full-duplex operation.

     half-duplex  Force half-duplex operation.

     The interface will operate in half-duplex mode if no media option is

     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.

     The axe device driver first appeared in OpenBSD 3.6.

     The axe driver was written by Bill Paul <> and ported
     to OpenBSD by Greg Taleck <>.
