_NDIS_RSS_PROCESSOR structure

Description

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

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.
