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

     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):


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

     All NICs supported	by the msk driver have TCP/UDP/IP checksum offload for
     transmit, TCP segmentation	offload	(TSO), hardware	VLAN tag stripping/in-
     sertion features and an interrupt moderation mechanism as well as a
     64-bit multicast hash filter.  The	Yukon II supports TBI (ten bit inter-
     face) and GMII transceivers, which	means it can be	used with either cop-
     per or 1000baseX fiber applications.

     The Yukon II also supports	Jumbo Frames (up to 9022 bytes), which can be
     configured	via the	interface MTU setting.	Selecting an MTU larger	than
     1500 bytes	with the ifconfig(8) utility configures	the adapter to receive
     and 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 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

     100baseTX	  Set 100Mbps (Fast Ethernet) operation.  The ifconfig(8)
		  mediaopt option can also be used to select either
		  full-duplex or half-duplex modes.

     1000baseTX	  Set 1000baseTX 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 1000baseTX

     link0  With 1000baseTX cards, establishing	a link between two ports re-
	    quires 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 mas-
	    ter	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).

     The msk driver provides support for various NICs based on the Mar-
     vell/SysKonnect Yukon II based Gigabit Ethernet controller	chips, includ-

     +o	 SysKonnect SK-9Sxx Gigabit Ethernet
     +o	 SysKonnect SK-9Exx Gigabit Ethernet

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

	     This tunable disables MSI support on the Ethernet hardware.  The
	     default value is 0.

     The following variables are available as both sysctl(8) variables and
     loader(8) tunables:

	     Maximum amount of Rx events to be processed in the	event loop be-
	     fore rescheduling a taskqueue.  The accepted range	is 30 to 256,
	     the default value is 128 events.  The interface does not need to
	     be	brought	down and up again before a change takes	effect.

     altq(4), arp(4), miibus(4), netintro(4), ng_ether(4), vlan(4),

     The msk driver was	written	by Pyun	YongHyeon <>	and it
     is	based on sk(4) and Marvell's FreeBSD driver.  It first appeared	in
     FreeBSD 7.0 and FreeBSD 6.3.
