.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for the SysKonnect SK-984x and SK-982x series PCI
|
|
gigabit ethernet adapters, including the following:
|

.El
|
|
.Pp
|
|
The SysKonnect adapters consist of two main components: the XaQti Corp.
|
|
XMAC II gigabit MAC and the SysKonnect GEnesis controller ASIC.
|
|
The
|
|
XMAC provides the gigabit MAC and PHY support while the GEnesis
|
|
provides an interface to the PCI bus, DMA support, packet buffering
|
|
and arbitration.
|
|
The GEnesis can control up to two XMACs simultaneously,
|
|
allowing dual-port NIC configurations.
|
|
.Pp
|
|
The SK-982x 1000baseT adapters also include a Broadcom BCM5400 1000baseTX
|
|
PHY which is used in place of the XMAC's internal PHY.
|
|
The Broadcom PHY is connected to the XMAC via its GMII port.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver configures dual port SysKonnect adapters such that each XMAC
|
|
is treated as a separate logical network interface.
|
|
Both ports can
|
|
operate independently of each other and can be connected to separate
|
|
networks.
|
|
The SysKonnect driver software currently only uses the
|
|
second port on dual port adapters for failover purposes: if the link
|
|
on the primary port fails, the SysKonnect driver will automatically
|
|
switch traffic onto the second port.
|
|
.Pp
|
|
Also supported is the Marvell Semiconductor 88E1000* gigabit PHY.
|
|
.Pp
|
|
The XaQti XMAC II supports full and half duplex operation with
|
|
autonegotiation.
|
|
The XMAC also supports unlimited frame sizes.
|
|
Support for jumbo frames is provided 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:
|
|
.Pp
|
|
.Bl -tag -width xxxxxxxxxxxxxxxxxxxx
|
|
.It 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 1000baseTX
|
|
Set 1000baseTX operation over twisted pair.
|
|
This is only available
|
|
for SK-982x series adapters with 1000baseT ports.
|
|
Both
|
|
.Ar full-duplex
|
|
and
|
|
.Ar half-duplex
|
|
modes are supported.
|
|
.It 1000baseSX
|
|
Set 1000Mbps (gigabit ethernet) operation.
|
|
Both
|
|
.Ar full-duplex
|
|
and
|
|
.Ar half-duplex
|
|
modes are supported.
|
|
.El
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver supports the following media options:
|
|
.Pp
|
|
.Bl -tag -width xxxxxxxxxxxxxxxxxxxx
|
|
.It full-duplex
|
|
Force full duplex operation
|
|
.It half-duplex
|
|
Force half duplex operation.
|
|
.El
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver also supports one special link option for 1000baseTX cards:
|
|
.Pp
|
|
.Bl -tag -width xxxxxxxxxxxxxxxxxxxx
|
|
.It link0
|
|
With 1000baseTX cards, establishing a link between two ports requires
|
|
that one port be configured as a master and the other a slave.
|
|
With autonegotiation,
|
|
the master/slave settings will be chosen automatically.
|
|
However when manually selecting the link state, it is necessary to
|
|
force one side of the link to be a master and the other a slave.
|
|
The
|
|
.Nm
|
|
driver configures the ports as slaves by default.
|
|
Setting the
|
|
.Ar link0
|
|
flag with
|
|
.Xr ifconfig 8
|
|
will set a port as a master instead.
|
|
.El
|
|
.Pp

|
|
.Xr ifconfig 8 .

.Sh DIAGNOSTICS
|
|
.Bl -diag
|
|
.It "sk%d: couldn't map memory"
|
|
A fatal initialization error has occurred.
|
|
.It "sk%d: couldn't map ports"
|
|
A fatal initialization error has occurred.
|
|
.It "sk%d: couldn't map interrupt"
|
|
A fatal initialization error has occurred.
|
|
.It "sk%d: no memory for softc struct!"
|
|
The driver failed to allocate memory for per-device instance information
|
|
during initialization.
|
|
.It "sk%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 "sk%d: no memory for jumbo buffers!"
|
|
The driver failed to allocate memory for jumbo frames during
|
|
initialization.
|
|
.It "sk%d: watchdog timeout"
|
|
The device has stopped responding to the network, or there is a problem with
|
|
the network connection (cable).
