DESCRIPTION
The
driver provides support for USB Ethernet adapters based on the ASIX
Electronics AX88172, AX88178 and AX88772 USB 2.0 chipsets.
The AX88172 and AX88178 are USB 2.0 devices that contain a 10/100
Ethernet MAC with MII interface and are designed to work with both
Ethernet and HomePNA transceivers.
The AX88772 will additionally support 10/100/1000 MACs.
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 endpoints.
The
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 the
/etc/rc.conf
file.
10baseT/UTP
Set 10Mbps operation.
The
mediaopt
option can also be used to enable
full-duplex
operation.
Not specifying
full-duplex
implies
half-duplex
mode.
100baseTX
Set 100Mbps (Fast Ethernet) operation.
The
mediaopt
option can also be used to enable
full-duplex
operation.
Not specifying
full-duplex
implies
half-duplex
mode.
The
driver supports the following media options:
full-duplex
Force full duplex operation.
The interface will operate in
half duplex mode if this media option is not specified.
For more information on configuring this device, see
ifconfig(8).
