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.
