    Hello guys,

    one problem concerning ProtocolReceive in NDIS IM driver. I see the
    functions indicates up the data received using MacReceiveContext with
    the NDIS_HANDLE MacReceiveContext parameter ( the second parameter ).
    If data received is not enough, I call NdisTransferData to get the
    rest of the packet, and I wnat to delay the indication until
    NdisTransferData returns successfull. I want to indicate the receive
    in the ProtocolTransferDataComplete handler. The problem is, what
    function should I use to indicate and, if NdisMEthIndicateReceive is
    the answer ( for 802_3 ) then what parameter should I pass in the
    MacReceiveContext?

    Thanks.

    MacReceiveContext – is the context of Packet Receive Operation.
    You can pass any handle there, but be ready to be called at MiniportTransferData with this very handle. And you’ll have to copy the data of the packet for that handle.
    Do I make myself clear ?

    thnks GeN, it’s clear. One more question – the MiniportTransferData will be called before Ndis..Indicate.. returns? So – am I free to release the handle upon exit of ProtocolTransferDataComplete ( from where I do the indication )?

    Thnks a lot.
