Description

The NET_BUFFER_LIST_SET_HASH_FUNCTION macro sets the hash function information in a NET_BUFFER_LIST structure.

Parameters

`Nbl`

A pointer to a NET_BUFFER_LIST structure.

`HashFunction`

The hash function that is used. For more information, see RSS Hashing Functions.

The hash function can be one of the following:

NdisHashFunctionToeplitz
NdisHashFunctionReserved1

A NIC (or its miniport driver) uses the receive side scaling (RSS) hashing function to calculate an RSS hash value.

For more information about the hashing functions, see RSS Hashing Functions.
