NET_ADAPTER_RECEIVE_SCALING_HASH_SECRET_KEY structure (netreceivescaling.h)

  • Article

The NET_ADAPTER_RECEIVE_SCALING_HASH_SECRET_KEY structure contains secret key data to verify RSS hash calculations.

Syntax

typedef struct _NET_ADAPTER_RECEIVE_SCALING_HASH_SECRET_KEY {
  UINT8  *Key;
  SIZE_T Length;
} NET_ADAPTER_RECEIVE_SCALING_HASH_SECRET_KEY;

Members

Key

The secret key. This member is 40 bytes (320 bits) for the NetAdapterReceiveScalingHashTypeToeplitz hash function.

Length

The length, in bytes, of Key.

Remarks

NetAdapterCx provides the secret key to NIC client drivers when it invokes the EvtNetAdapterReceiveScalingSetHashSecretKey callback function. The NIC then uses this secret key to verify its calculations for the RSS hash function.
