+SysKonnect SK-984x PCI gigabit ethernet adapter driver
+.Sh SYNOPSIS
+.Cd "device sk0"
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for the SysKonnect SK-984x series PCI
+gigabit ethernet adapters, including the following:
+.Bl -bullet -offset indent
+.It
+SK-9841 SK-NET GE-LX single port, single mode fiber adapter
+.It
+SK-9842 SK-NET GE-SX single port, multimode fiber adapter
+.It
+SK-9843 SK-NET GE-LX dual port, single mode fiber adapter
+.It
+SK-9844 SK-NET GE-SX duak port, multimode fiber adapter
+.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 suspport 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
+.Nm
+driver configures dual port SysKonnect adapters such that each XMAC
+is treated as a separate logical network interface. Both ports can
+operate indepenently 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
+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 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

+For more information on configuring this device, see
+.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).
