.\"O .B sk98lin
.\"O is the Gigabit Ethernet driver for Marvell and SysKonnect network adapter cards.

.\"O any Yukon compliant chipset.

.\"O When loading the driver using insmod, parameters for the network adapter cards
.\"O might be stated as a sequence of comma separated commands.
.\"O If for instance two network adapters are installed and AutoNegotiation on
.\"O Port A of the first adapter should be ON,
.\"O but on the Port A of the second adapter switched OFF, one must enter:

.\"O for all ports of the installed network adapter cards.
.\"O Those files are named

.\"O If loading is finished, any desired IP address can be

.\"O interface using the
.\"O .BR ifconfig (8)

.\"O This causes the adapter to connect to the Ethernet and to display a status

.\"O The
.\"O .B sk98lin
.\"O also supports large frames (also called jumbo frames).
.\"O Using jumbo frames can improve throughput tremendously when
.\"O transferring large amounts of data.
.\"O To enable large frames, the MTU (maximum transfer unit) size
.\"O for an interface is to be set to a high value.
.\"O The default MTU size is 1500 and can be changed up to 9000 (bytes).
.\"O Setting the MTU size can be done when assigning the IP address
.\"O to the interface or later by using the
.\"O .BR ifconfig (8)
.\"O command with the mtu parameter.
.\"O If for instance eth0 needs an IP
.\"O address and a large frame MTU size,
.\"O the following two commands might be used:

.\"O Note that large frames can only be used if permitted by
.\"O your network infrastructure.
.\"O This means, that any switch being used in your Ethernet must
.\"O also support large frames.
.\"O Quite some switches support large frames,
.\"O but need to be configured to do so.
.\"O Most of the times, their default setting is to support only
.\"O standard frames with an MTU size of 1500 (bytes).
.\"O In addition to the switches inside the network,
.\"O all network adapters that are to be used must also be
.\"O enabled regarding jumbo frames.
.\"O If an adapter is not set to receive large frames it will simply drop them.

.\"O RLMT monitors the status of the port.
.\"O If the link of the active port fails,
.\"O RLMT switches immediately to the standby link.
.\"O The virtual link is maintained as long as at least one "physical" link is up.
.\"O This parameters states how RLMT should monitor both ports.
.\"O Possible values are:

.I CheckLocalPort
.\"O In this mode, RLMT monitors the network path between the two
.\"O ports of an adapter by regularly exchanging packets between them.
.\"O This mode requires a network configuration in which the
.\"O two ports are able to "see" each other (i.e., there
.\"O must not be any router between the ports).

.I DualNet
.\"O In this mode, ports A and B are used as separate devices.
.\"O If you have a dual port adapter, port A will be configured as

.\"O Both ports can be used independently with distinct IP addresses.
.\"O The preferred port setting is not used.

.\"O and

.\"O are designed to operate in configurations where a

.\"O Moreover, they are not designed to work where adapters are
