NAME

     sk -- SysKonnect SK-984x and SK-982x PCI Gigabit Ethernet adapter driver


SYNOPSIS

     device miibus
     device sk


DESCRIPTION

     The sk driver provides support for the SysKonnect SK-984x and SK-982x
     series PCI Gigabit Ethernet adapters.

     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.

     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.

     The sk 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 net-
     works.  The SysKonnect driver software currently only uses the second
     port on dual port adapters for failover purposes: if the link on the pri-
     mary port fails, the SysKonnect driver will automatically switch traffic
     onto the second port.

     Also supported is the Marvell Semiconductor 88E1000* gigabit PHY.

     The XaQti XMAC II supports full and half duplex operation with autonego-
     tiation.  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 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.

     The sk driver supports the following media types:

     autoselect 	   Enable autoselection of the media type and options.
			   The user can manually override the autoselected
			   mode by adding media options to the /etc/rc.conf
			   file.

     1000baseTX 	   Set 1000baseTX operation over twisted pair.	This
			   is only available for SK-982x series adapters with
			   1000baseT ports.  Both full-duplex and half-duplex
			   modes are supported.

     1000baseSX 	   Set 1000Mbps (Gigabit Ethernet) operation.  Both
			   full-duplex and half-duplex modes are supported.

     The sk driver supports the following media options:

			   master and the other one as slave.  With autonego-
			   tiation, 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
			   sk driver configures the ports as slaves by
			   default.  Setting the link0 flag with ifconfig(8)
			   will set a port as a master instead.

     For more information on configuring this device, see ifconfig(8).

DIAGNOSTICS

     sk%d: couldn't map memory	A fatal initialization error has occurred.

     sk%d: couldn't map ports  A fatal initialization error has occurred.

     sk%d: couldn't map interrupt  A fatal initialization error has occurred.

     sk%d: no memory for softc struct!	The driver failed to allocate memory
     for per-device instance information during initialization.

     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.

     sk%d: no memory for jumbo buffers!  The driver failed to allocate memory
     for jumbo frames during initialization.

     sk%d: watchdog timeout  The device has stopped responding to the network,
     or there is a problem with the network connection (cable).
