•   SysKonnect SK-9E81 single port, multimode fiber adapter
•   SysKonnect SK-9E82 dual port, multimode fiber adapter
•   SysKonnect SK-9E91 single port, single mode fiber adapter
•   SysKonnect SK-9E92 dual port, single mode fiber adapter
•   SysKonnect SK-9S21 single port, copper adapter
•   SysKonnect SK-9S22 dual port, copper adapter

The Yukon-2 88E802x, 88E805x, 88E806x, and 88E807x also support a frame size of up to 9000 bytes. 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 transmit Jumbo frames.

The msk 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 msk 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 msk0 media.
