.Sh DESCRIPTION
The
.Nm
driver provides support for Marvell Yukon-2 88E802x, 88E805x, and 88E806x
based Gigabit Ethernet adapters and 88E803x/88E804x based Fast Ethernet
adapters, including the following:

.El
.Pp
The Yukon-2 88E802x, 88E805x, and 88E806x 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
.Xr ifconfig 8
utility configures the adapter to transmit Jumbo frames.
Using Jumbo frames can greatly improve performance for certain tasks,
such as file transfers and data streaming.
.Pp
The
.Nm
driver supports the following media types:
.Bl -tag -width 1000baseSX
.It Cm autoselect
Enable autoselection of the media type and options.
The user can manually override
the autoselected mode by adding media options to the appropriate
.Xr hostname.if 5
file.
.It Cm 10baseT
Set 10Mbps operation.
The
.Xr ifconfig 8
.Ic mediaopt
option can also be used to select either
.Cm full-duplex
or
.Cm half-duplex
modes.
.It Cm 100baseTX
Set 100Mbps (Fast Ethernet) operation.
The
.Xr ifconfig 8
.Ic mediaopt
option can also be used to select either
.Cm full-duplex
or
.Cm half-duplex
modes.
.It Cm 1000baseT
Set 1000baseT (Gigabit Ethernet) operation over twisted pair.
Both
.Cm full-duplex
and
.Cm half-duplex
modes are supported.
.It Cm 1000baseSX
Set 1000Mbps (Gigabit Ethernet) operation.
Both
.Cm full-duplex
and
.Cm half-duplex
modes are supported.
.El
.Pp
The
.Nm
driver supports the following media options:
.Bl -tag -width full-duplex
.It Cm full-duplex
Force full duplex operation.
.It Cm half-duplex
Force half duplex operation.
.El
.Pp
For more information on configuring this device, see
.Xr ifconfig 8 .
To view a list of media types and options supported by the card, try
.Ic ifconfig -m <device> .
For example,
.Ic ifconfig -m msk0 .
