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`.
