VxWorks 5.5 <strong>BSP</strong> Developer’s <strong>Guide</strong> The routine is of the following form: STATUS endPacketDataGet ( M_BLK_ID pBuff, /* packet data and address information */ LL_HDR_INFO* pLinkHdrInfo /* structure to hold link-level info. */ ) The parameters are: pBuff Expects a pointer to the mBlk that still contains both header and packet data. pLinkHdrInfo Returns an LL_HDR_INFO structure containing header information that is dependent upon the particular data-link layer that the END implements. For more information, see Tracking Link-Level Information: LL_HDR_INFO, p.287. Return Addressing Information: endPacketAddrGet( ) This routine must retrieve the address information associated with a packet. Some common cases are provided in endLib. The last two parameters are used for networks where the hardware source and destination addresses at the ultimate endpoint can differ from the local source and destination addresses. This routine should return OK or ERROR. If there is an error, it must set errno. The routine is of the following form: STATUS endPacketAddrGet ( M_BLK_ID pMblk, /* M_BLK_ID of the packet */ M_BLK_ID pSrc, /* local source of packet */ M_BLK_ID pDst, /* local destination of packet */ M_BLK_ID pESrc, /* end source of packet */ M_BLK_ID pEDst /* end destination of packet */ ) pMblk Expects a pointer to the mBlk structure from which you want to extract address information. pSrc Expects NULL or a pointer to the mBlk structure into which to write the extracted source address (local) of the packet. 300
H Implementing a MUX-Based Network Interface Driver pDst Expects NULL or a pointer to the mBlk structure into which to write the extracted destination address (local) of the packet. pESrc Expects NULL or a pointer to the mBlk structure into which to write the extracted source address (end, if different) of the packet.end source of packet. pEDst Expects NULL or a pointer to the mBlk structure into which to write the extracted destination address (end, if different) of the packet. H.6 Writing Protocols That Use the MUX API This section describes how to port protocols to the MUX-based model. As shown in Figure H-1, MUX-based protocols bind themselves to the MUX from above and network interface drivers (ENDs) bind themselves to the MUX from below. Thus, a protocol is layered on top of the MUX, which is layered on top of a network interface driver. The responsibilities of each is given in Table H-3. Table H-3 Layers and Responsibilities Layer Protocol MUX Network Interface Driver Responsibilities Interface to the transport layer, and, through it, to application programs. Copying packet data if needed. Loading and unloading drivers. Binding and unbinding protocols. Calling each bound protocol’s receive routine. Managing memory for buffer loaning. Dealing with hardware. Loading a driver into the system. Unloading a driver from the system. Loaning buffers to upper layers. H 301
