-f Forwarding traffic scenario.
This option must be followed by two connection names. The tuning in this case is code-
pendent.
This option automatically sets:
• SendCompletionMethod = 1
• RecvCompletionMethod = 0
• *ReceiveBuffers = 4096
• UseRSSForRawIP = 0
• UseRSSForUDP = 0
Additionally, this option chooses the best processors to assign to:
• DefaultRecvRingProcessor
• TxInterruptProcessor
• TxForwardingProcessor
• In Operating Systems support NDIS6.2:
RssBaseProcNumber
MaxRssProcessors
• In Operating Systems support NDIS6.3:
NumRSSQueues
RssMaxProcNumber
-m Manual configuration
This option must be followed by one connection name.
This option assigns the provided base and number of CPUs to:
• *RssBaseProcNumber
• *MaxRssProcessors
Additionally, this option assigns the following with processors inside the range:
• DefaultRecvRingProcessor
• TxInterruptProcessor
-r Restore default settings.
This option can be followed by one or two connection names.
This option automatically sets the driver registry values back to their default values:
• SendCompletionMethod = 0
• RecvCompletionMethod = 2
• *ReceiveBuffers = 1024
• UseRSSForRawIP = 1
• DefaultRecvRingProcessor = -1
• TxInterruptProcessor = -1
• TxForwardingProcessor = -1
• UseRSSForUDP = 1
• In Operating Systems support NDIS6.2:
MaxRssProcessors = 8
• In Operating Systems support NDIS6.3:
NumRSSQueues = 8
-c1 Specifies first connection name. See examples
-c2 Specifies second connection name. See examples
-b Specifies base RSS processor number. See examples.
Used for manual option (-m) only.
-n Specifies number of RSS processors. See examples.
Used for manual option (-m) only.
