It is recommended to download the latest version of the driver from the

driver, the Linux kernel has to be patched before the driver can be
installed. For details on how to patch a Linux kernel, refer to the

Interrupt moderation is employed to limit the maxmimum number of interrupts
NOTE: The modes CheckLocalPort and CheckSeg are meant to operate in the driver has to serve. That is, one or more interrupts (which indicate any
configurations where a network path between the ports on one transmit or receive packet to be processed) are queued until the driver
adapter exists. Especially, they are not designed to work where processes them. When queued interrupts are to be served, is determined by the
adapters are connected back-to-back. 'IntsPerSec' parameter, which is explained later below.
Possible modes:
-- None - No interrupt moderation is applied on the adapter card.
Therefore, each transmit or receive interrupt is served immediately
as soon as it appears on the interrupt line of the adapter card.
-- Static - Interrupt moderation is applied on the adapter card.
All transmit and receive interrupts are queued until a complete
moderation interval ends. If such a moderation interval ends, all
queued interrupts are processed in one big bunch without any delay.
The term 'static' reflects the fact, that interrupt moderation is
always enabled, regardless how much network load is currently
passing via a particular interface. In addition, the duration of
the moderation interval has a fixed length that never changes while
the driver is operational.
-- Dynamic - Interrupt moderation might be applied on the adapter card,
depending on the load of the system. If the driver detects that the
system load is too high, the driver tries to shield the system against
too much network load by enabling interrupt moderation. If - at a later
time - the CPU utilizaton decreases again (or if the network load is
negligible) the interrupt moderation will automatically be disabled.
Interrupt moderation should be used when the driver has to handle one or more
interfaces with a high network load, which - as a consequence - leads also to a
high CPU utilization. When moderation is applied in such high network load
situations, CPU load might be reduced by 20-30%.
NOTE: The drawback of using interrupt moderation is an increase of the round-
trip-time (RTT), due to the queueing and serving of interrupts at dedicated
moderation times.
Interrupts per second
---------------------
Parameter: IntsPerSec
Values: 30...40000 (interrupts per second)
Default: 2000
This parameter is only used, if either static or dynamic interrupt moderation
is used on a network adapter card. Using this paramter if no moderation is
applied, will lead to no action performed.
This parameter determines the length of any interrupt moderation interval.
Assuming that static interrupt moderation is to be used, an 'IntsPerSec'
parameter value of 2000 will lead to an interrupt moderation interval of
500 microseconds.
NOTE: The duration of the moderation interval is to be chosen with care.
At first glance, selecting a very long duration (e.g. only 100 interrupts per
second) seems to be meaningful, but the increase of packet-processing delay
is tremendous. On the other hand, selecting a very short moderation time might
compensate the use of any moderation being applied.
Preferred Port
--------------
Parameter: PrefPort
Values: A, B
Default: A
This is used to force the preferred port to A or B (on dual-port network
adapters). The preferred port is the one that is used if both are detected
as fully functional.
RLMT Mode (Redundant Link Management Technology)
------------------------------------------------
Parameter: RlmtMode
Values: CheckLinkState,CheckLocalPort, CheckSeg, DualNet
Default: CheckLinkState
RLMT monitors the status of the port. If the link of the active port
fails, RLMT switches immediately to the standby link. The virtual link is
maintained as long as at least one 'physical' link is up.
Possible modes:
-- CheckLinkState - Check link state only: RLMT uses the link state
reported by the adapter hardware for each individual port to
determine whether a port can be used for all network traffic or
not.
-- CheckLocalPort - In this mode, RLMT monitors the network path
between the two ports of an adapter by regularly exchanging packets
between them. This mode requires a network configuration in which
the two ports are able to "see" each other (i.e. there must not be
any router between the ports).
-- CheckSeg - Check local port and segmentation: This mode supports the
same functions as the CheckLocalPort mode and additionally checks
network segmentation between the ports. Therefore, this mode is only
to be used if Gigabit Ethernet switches are installed on the network
that have been configured to use the Spanning Tree protocol.
-- DualNet - In this mode, ports A and B are used as separate devices.
If you have a dual port adapter, port A will be configured as eth0
and port B as eth1. Both ports can be used independently with
distinct IP addresses. The preferred port setting is not used.
RLMT is turned off.
NOTE: RLMT modes CLP and CLPSS are designed to operate in configurations
where a network path between the ports on one adapter exists.
Moreover, they are not designed to work where adapters are connected
back-to-back.

(7) TROUBLESHOOTING 6 VLAN and Link Aggregation Support (IEEE 802.1, 802.1q, 802.3ad)
=================== ==================================================================
The Marvell Yukon/SysKonnect Linux drivers are able to support VLAN and
Link Aggregation according to IEEE standards 802.1, 802.1q, and 802.3ad.
These features are only available after installation of open source
modules available on the Internet:
For VLAN go to: http://scry.wanfear.com/~greear/vlan.html
For Link Aggregation go to: http://www.st.rim.or.jp/~yumo
NOTE: SysKonnect GmbH does not offer any support for these open source
modules and does not take the responsibility for any kind of
failures or problems arising in connection with these modules.
NOTE: Configuring Link Aggregation on a SysKonnect dual link adapter may
cause problems when unloading the driver.
