NAME
msk - Marvell/SysKonnect Yukon II Gigabit Ethernet adapter driver

SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file:

device miibus
device msk

Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

    if_msk_load="YES"

DESCRIPTION
The msk device driver provides support for various NICs based on the Marvell/SysKonnect Yukon II Gigabit Ethernet controller chip.

All NICs supported by the msk driver have an interrupt moderation mechanism as well as a 64-bit multicast hash filter. The Yukon II supports TBI (ten bit interface) and GMII transceivers, which means it can be used with either copper or 1000baseX fiber applications.

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 rc.conf(5).

10baseT/UTP
    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 operation over twisted pair. The ifconfig(8) mediaopt option can also be used to select either full-duplex or half-duplex modes.

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.

The msk driver also supports one special link option for 1000baseT cards:

link0
    With 1000baseT cards, establishing a link between two ports requires that one port is configured as master and the other one as slave. With autonegotiation, 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 msk 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).

LOADER TUNABLES
Tunables can be set at the loader(8) prompt before booting the kernel or stored in loader.conf(5).

hw.mskc.msi.enable
    The driver supports MSI but it is turned off by default. It can be enabled by setting this tunable to 1.
