.Sh NAME
.Nm e1000g
.Nd Intel 1 Gigabit Client Ethernet Controller
.Sh SYNOPSIS
.Pa /dev/net/e1000g*
.Sh DESCRIPTION
The
.Nm
driver is a GLDv3 NIC driver for Intel 1 Gigabit Ethernet devices which
are often found as discrete PCI and PCI express add-on-cards and built
into many Intel chipsets and platforms.
.Pp
On most models, the device driver supports transmit and receive
checksumming, 9000 byte jumbo frames, large send offload
.Pq LSO ,
LED control and Ethernet Pause frames.
.Pp
For each device supported by the
.Nm
driver, a character special-file will be created for each instance.
The first instance would have id 0 and would be named
.Sy e1000g0
and found in the file system at
.Pa /dev/net/e1000g0 .
This device node supports the Data Link Provider Interface
.Pq DLPI
which is documented in
.Xr dlpi 4P .
.Xr libdlpi 3LIB
provides a more usable interface on top of that.
.Pp
For administrative control, the device can be manipulated through the
.Xr dladm 8
utility.
.Pp

driver supports many other Intel Gigabit parts.
.Sh CONFIGURATION
The
.Pa e1000g.conf
file contains some user configurable parameters, the format of which
is documented in
.Xr driver.conf 5 .
Generally, the use of
.Xr dladm 8
is recommended over editing the configuration file.
