.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for USB ethernet adapters based on the ASIX
|
|
Electronics AX88172 USB 2.0 chipset, including the following:
|
|

|
|
.El
|
|
.Pp
|
|
The AX88172 is a USB 2.0 device which contains a 10/100
|
|
ethernet MAC with MII interface and is designed to work with both
|
|
ethernet and HomePNA transceivers.
|
|
The AX88172 will operate with
|
|
both USB 1.x and USB 2.0 controllers, however performace with 1.x
|
|
contollers 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.
|
|
.Pp
|
|
The AX88172 supports 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.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver supports the following media types:
|
|
.Bl -tag -width ".Cm 10baseT/UTP"
|
|
.It Cm autoselect
|
|
Enable autoselection of the media type and options.
|
|
The user can manually override
|
|
the autoselected mode by adding media options to the
|
|
.Pa /etc/rc.conf
|
|
file.
|
|
.It Cm 10baseT/UTP
|
|
Set 10Mbps operation.
|
|
The
|
|
.Cm mediaopt
|
|
option can also be used to enable
|
|
.Cm full-duplex
|
|
operation.
|
|
Not specifying
|
|
.Cm full-duplex
|
|
implies
|
|
.Cm half-duplex
|
|
mode.
|
|
.It Cm 100baseTX
|
|
Set 100Mbps (fast ethernet) operation.
|
|
The
|
|
.Cm mediaopt
|
|
option can also be used to enable
|
|
.Cm full-duplex
|
|
operation.
|
|
Not specifying
|
|
.Cm full-duplex
|
|
implies
|
|
.Cm half-duplex
|
|
mode.
|

.Pp
|
|
The
|
|
.Nm
|
|
driver supports the following media options:
|
|
.Bl -tag -width ".Cm 10baseT/UTP"
|
|
.It Cm full-duplex
|
|
Force full duplex operation.
|
|
The interface will operate in
|
|
half duplex mode if this media option is not specified.
