Structure Description:

    This structure defines an RTLW81xx bulk out transfer. These transfers are
    allocated on demand and recycled when complete.

Members:

    ListEntry - Stores a pointer to the next and previous bulk out transfer
        on the devices free transfer list.

    Device - Stores a pointer to the RTLW81 device that owns the transfer.

    UsbTransfer - Stores a pointer to the USB transfer that belongs to this
        SM95 transfer for the duration of its existence.

    Packet - Stores a pointer to the network packet buffer whose data is being
        sent by the USB transfer.

    EndpointIndex - Stores the index into the device's out endpoint array for
        the endpoint to which the transfer belongs.

Routine Description:

    This routine sends data through the network.

Arguments:

    PacketList - Supplies a pointer to a list of network packets to send. Data

Return Value:

    STATUS_RESOURCE_IN_USE if some or all of the packets were dropped due to
    the hardware being backed up with too many packets to send.

    Other failure codes indicate that none of the packets were sent.
