axe - ASIX Electronics AX88x7x/760 USB Ethernet driver
To compile this driver into the kernel, place the following lines in your
kernel configuration file:
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
Ethernet and HomePNA transceivers. The AX88178 has a 10/100/1000
Ethernet MAC with GMII/RGMII interface for interfacing with Gigabit
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
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
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).
The axe driver supports ASIX Electronics

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
