Routine Description:


    The Rtl8139Send request instructs a driver to transmit packets through
    the adapter onto the medium.

Arguments:

    MiniportAdapterContext - Context registered with the wrapper, really
        a pointer to the adapter.

    PacketArray - A pointer to a descriptor for the packet that is to be
    transmitted.

    NumberOfPackets

    Packet - A pointer to a descriptor for the packet that is to be
    transmitted.

    SendFlags - Optional send flags

Notes:

    This miniport driver will always accept a send.  This is because
    the Rtl8139 has limited send resources and the driver needs packets
    to copy to the adapter immediately after a transmit completes in
    order to keep the adapter as busy as possible.

    This is not required for other adapters, as they have enough
    resources to keep the transmitter busy until the wrapper submits
    the next packet.
