.Sh NAME
|
|
.Nm sge
|
|
.Nd Silicon Integrated Systems SiS190/191 Fast/Gigabit Ethernet driver
|
|
.Sh SYNOPSIS
|
|
To compile this driver into the kernel,
|
|
place the following lines in your
|
|
kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "device miibus"
|
|
.Cd "device sge"
|
|
.Ed
|
|
.Pp
|
|
Alternatively, to load the driver as a
|
|
module at boot time, place the following line in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
if_sge_load="YES"
|
|
.Ed
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
device driver provides support for SiS190 Fast Ethernet
|
|
controllers and SiS191 Fast/Gigabit Ethernet controllers.
|
|
.Pp
|
|
All LOMs supported by the
|
|
.Nm
|
|
driver have TCP/UDP/IP checksum offload for transmit and receive,
|
|
TCP segmentation offload (TSO), hardware VLAN tag stripping/insertion
|
|
features.
|
|
Due to lack of documentation Wake On Lan (WOL), Jumbo frame and an
|
|
interrupt moderation mechanism are not supported yet.
|
|
.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
|
|
.Xr rc.conf 5 .
|
|
.It Cm 10baseT/UTP
|
|
Set 10Mbps operation.
|
|
.It Cm 100baseTX
|
|
Set 100Mbps (Fast Ethernet) operation.
|
|
.It Cm 1000baseTX
|
|
Set 1000baseTX operation over twisted pair.
|
|
.El
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver supports the following media options:
|
|
.Bl -tag -width ".Cm full-duplex"
|
|
.It Cm full-duplex
|
|
Force full duplex operation.
|
|
.It Cm half-duplex
|
|
Force half duplex operation.
