NDIS_RSS_PROCESSOR structure (ntddndis.h)

  • Article

The NDIS_RSS_PROCESSOR structure specifies information about a processor in the local computer for receive side scaling (RSS).

Syntax

typedef struct _NDIS_RSS_PROCESSOR {
  PROCESSOR_NUMBER ProcNum;
  USHORT           PreferenceIndex;
  USHORT           Reserved;
} NDIS_RSS_PROCESSOR, *PNDIS_RSS_PROCESSOR;

Members

ProcNum

The processor number that is assigned to the processor.

PreferenceIndex

The preference rating of the processor, which is based on Non-Uniform Memory Access (NUMA) distance. A lower value for PreferenceIndex indicates a smaller NUMA distance to the miniport driver.

When choosing between multiple processors, miniport drivers should select the processor with a lower
PreferenceIndex value. This results in less overhead for the driver.

Reserved

Reserved for NDIS.

Remarks

The NDIS_RSS_PROCESSOR structure is used in the NDIS_RSS_PROCESSOR_INFO structure.

Requirements

Minimum supported client Supported in NDIS 6.20 and later.
