|
|
.Nd MosChip MCS7730/7830/7832 10/100 USB Ethernet device
|
|
.Sh SYNOPSIS
|
|
.Cd "mos* at uhub?"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for USB Ethernet adapters based on the MosChip
|
|
MCS7730, MCS7830, and MCS7832 USB 2.0 chipsets, including the
|
|
following:
|
|
.Pp
|
|
.Bl -tag -width Ds -offset indent -compact
|
|
.It Delock 61147
|
|
.It Sitecom LN-030
|
|
.It Syba SY-U2LAN
|
|
.El
|
|
.Pp
|
|
All adapters operate with either USB 1.x, 2.0, or 3.x controllers,
|
|
though performance with 1.x controllers is 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
|
|
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.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver supports the following media types:
|
|
.Bl -tag -width "autoselect"
|
|
.It 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
|
|
.Xr ifconfig.if 5
|
|
file.
|
|
.It 10baseT
|
|
Set 10Mbps operation.
|
|
.It 100baseTX
|
|
Set 100Mbps (Fast Ethernet) operation.
|
|
.El
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver supports the following media options:
|
|
.Bl -tag -width "full-duplex"
|
|
.It full-duplex
|
|
Force full-duplex operation.
|
|
.It half-duplex
|
|
Force half-duplex operation.
|
|
.El
|
|
.Pp
