NIC Driver Real-Time Network Device (RTND) Functions

Below are the supported NIC Driver Real-Time Network Device (RTND) functions:

Function	Description
RtndConfigure	Called for each instance of the driver when the driver should configure the NIC hardware. This function should set up receive buffers/transmit buffers, card modes, events, etc.
RtndInitialize	Called by the stack when an instance of a driver is being first brought online. This is the first routine in a driver that is called by the stack.
RtndIoctl	Called when the stack requires that the driver configure certain NIC modes or characteristics.
RtndReceive	Called by the RT-TCP/IP Stack’s receive thread. The Stack is notified of a waiting receive packet when the IST routine calls tnNotifyRecv. Then the Stack calls RtndReceive presumably from a lower priority thread than the IST.
RtndRequest	Forwards a request to the underlying driver to query the requested capabilities and/or statistics of the Rtx converted NIC card.
RtndTransmit	Called when the stack requires that the driver transmit a packet (pointed to by the parameter mp). The packet is in a structure format required by the RtxTcpIp Stack, which the driver does not need to know. The driver should use the RtnDecodePacket routine to obtain the network device (ndp), data pointer and data length for the packet.
RtndUpDown	Called when the stack requires that the driver start (or stop) a particular NIC card.
