DESCRIPTION

The sk driver provides support for SysKonnect GEnesis and Marvell Yukon 88E8001, 88E8003 and 88E8010 based Gigabit Ethernet adapters, including the following:
The SysKonnect based adapters consist of two main components: the XaQti Corp. XMAC II Gigabit MAC (sk) and the SysKonnect GEnesis controller ASIC (skc). 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 Marvell based adapters are a single integrated circuit, but are still presented as a separate MAC (sk) and controller ASIC (skc).
The GEnesis and Yukon 88E8001, 88E8003 and 88E8010 also support jumbo frames.
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 appropriate hostname.if(5) file.
 
 
10baseT
Set 10Mbps operation. The ifconfig(8) mediaopt option can also be used to select either full-duplex or half-duplex modes.
 
 
100baseTX
Set 100Mbps (Fast Ethernet) operation. The ifconfig(8) mediaopt option can also be used to select either full-duplex or half-duplex modes.
 
 
1000baseT
Set 1000baseT (Gigabit Ethernet) operation over twisted pair. 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:
 
 
full-duplex
Force full duplex operation.
 
 
half-duplex
Force half duplex operation.
For more information on configuring this device, see ifconfig(8). To view a list of media types and options supported by the card, try ifconfig <device> media. For example, ifconfig sk0 media.
