The AX88172, AX88178, and AX88772 are USB 2.0 devices designed to work with either Ethernet or HomePNA transceivers. The AX88172 and AX88772 contain 10/100 Ethernet MACs with MII interfaces. The AX88178 contains a 10/100/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 endpoints.
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 specified.
For more information on configuring this device, see ifconfig(8).

DIAGNOSTICS

axe0: 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.
axe0: no memory for rx list
The driver failed to allocate an mbuf for the receiver ring.
