The NET_BUFFER_LIST_GET_HASH_TYPE macro gets the hash type information from a NET_BUFFER_LIST structure.
A pointer to a NET_BUFFER_LIST structure.
NET_BUFFER_LIST_GET_HASH_TYPE returns the hash type of the specified NET_BUFFER_LIST structure.
The hash type is an OR value of valid combinations of the following flags:
- NDIS_HASH_IPV4
- NDIS_HASH_TCP_IPV4
- NDIS_HASH_IPV6
- NDIS_HASH_TCP_IPV6
- NDIS_HASH_IPV6_EX
- NDIS_HASH_TCP_IPV6_EX
For more information about hash types and the valid combinations of these flags, see RSS Hashing Types).
A NIC (or its miniport driver) uses the receive side scaling (RSS) hash type to identify the portion of received network data that is used to calculate an RSS hash value.
For more information about the hash type, see RSS Hashing Types.
