|
|

|
|
.Sh SYNOPSIS
|
|
.Cd "device miibus"
|
|
.Cd "device lge"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for various NICs based on the Level 1 LXT1001
|
|
NetCellerator gigabit ethernet controller chip, including the
|
|
following:
|
|
.Pp
|
|
.Bl -bullet -compact
|
|
.It
|
|
SMC TigerCard 1000 (SMC9462SX)
|
|
.It
|
|
D-Link DGE-500SX
|
|
.El
|
|
.Pp
|
|
These NICs are capable of 1000Mbps speeds over fiber optic cable.
|
|
The LXT1001 also supports a GMII port for use with 10/100/1000 copper
|
|
PHYs, however there aren't currently any NICs on the market that use
|
|
this feature.
|
|
.Pp
|
|
The LXT1001 supports TCP/IP checksum offload for receive and
|
|
VLAN-based filtering as well as a 64-bit multicast hash filter.
|
|
It also supports jumbo frames, which can be configured
|
|
via the interface MTU setting.
|
|
Selecting an MTU larger than 1500 bytes with the
|
|
.Xr ifconfig 8
|
|
utility configures the adapter to receive and transmit jumbo frames.
|
|
Using jumbo frames can greatly improve performance for certain tasks,
|
|
such as file transfers and data streaming.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver supports the following media types:
|
|
.Bl -tag -width ".Cm 1000baseSX"
|
|
.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 1000baseSX
|
|
Set 1000baseSX operation over fiber optic cable.
|
|
Both
|
|
.Cm full-duplex
|
|
and
|
|
.Cm half-duplex
|
|
modes are supported.
|
|
.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.
|
|
.El
|
|
.Pp
|
|

|
|
.Xr ifconfig 8 .

|
.Sh DIAGNOSTICS
|
|
.Bl -diag
|
|
.It "lge%d: couldn't map memory"
|
|
A fatal initialization error has occurred.
|
|
.It "lge%d: couldn't map ports"
|
|
A fatal initialization error has occurred.
|
|
.It "lge%d: couldn't map interrupt"
|
|
A fatal initialization error has occurred.
|
|
.It "lge%d: no memory for softc struct!"
|
|
The driver failed to allocate memory for per-device instance information
|
|
during initialization.
|
|
.It "lge%d: failed to enable memory mapping!"
|
|
The driver failed to initialize PCI shared memory mapping.
|
|
This might
|
|
happen if the card is not in a bus-master slot.
|
|
.It "lge%d: no memory for jumbo buffers!"
|
|
The driver failed to allocate memory for jumbo frames during
|
|
initialization.
|
|
.It "lge%d: watchdog timeout"
|
|
The device has stopped responding to the network, or there is a problem with
|
|
the network connection (cable).
