The NdisGetNetBufferListProtocolId function retrieves the protocol identifier from the NetBufferListInfo member of a NET_BUFFER_LIST structure.
NetBufferList [in]A pointer to a NET_BUFFER_LIST structure.
NdisGetNetBufferListProtocolId returns a protocol identifier as one of the following values:
| Return code | Description |
|---|---|
| NDIS_PROTOCOL_ID_DEFAULT | A default protocol driver identifier. |
| NDIS_PROTOCOL_ID_TCP_IP | The TCP/IP protocol identifier. |
| NDIS_PROTOCOL_ID_IPX | The IPX protocol identifier. |
| NDIS_PROTOCOL_ID_NBF | The NetBEUI protocol identifier. |
NDIS drivers can call the NdisGetNetBufferListProtocolId function to determine the type of protocol driver that created a NET_BUFFER_LIST structure. For example, miniport drivers that support TCP chimney offload can verify that a NET_BUFFER_LIST structure comes from a TCP protocol.
Protocol drivers that create NET_BUFFER_LIST structures should set the protocol identifier by calling the NdisSetNetBufferListProtocolId macro or by associating an identifier with a NET_BUFFER_LIST pool.
