TCP Checksum offload - zeroed TcpIpChecksumNetBufferListInfo RRS feed

  • Question

  • Hi, I am trying to implement TCP checksum offload on our NIC,

    I've added a call to NdisMSetMiniportAttributes for NDIS_MINIPORT_ADAPTER_OFFLOAD_ATTRIBUTES in miniport initialize with all the needed configurations

    But for some reason I keep getting zeros when reading TcpIpChecksumNetBufferListInfo from every TX

    tcpIpChecksumNetBufferListInfo.Value = NET_BUFFER_LIST_INFO(pCurrentWlanPacket, TcpIpChecksumNetBufferListInfo);

    Any idea why?

  • Without being able to see your code, it is very difficult to diagnose. Have you seen this?
