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.
XMAC provides the gigabit MAC and PHY support while the GEnesis
provides an interface to the PCI bus, DMA support, packet buffering
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 XMACs internal PHY.
The Broadcom PHY is connected to the XMAC via its GMII port.
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
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.
Also supported is the Marvell Semiconductor 88E100* gigabit PHY.
The XaQti XMAC II supports full and half duplex operation with
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
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.
driver supports the following media types:
Enable autoselection of the media type and options.
The user can manually override
the autoselected mode by adding media options to the
