VxWorks 5.5 <strong>BSP</strong> Developer’s <strong>Guide</strong> Your endMCastAddrDel( ) must also reconfigure the driver (in a hardware-specific way) so that the driver longer receives frames with the specified address. Getting the Multicast Address Table: endMCastAddrGet( ) Your endMCastAddrGet( ) must get a table of multicast addresses and return it in the buffer referenced in the pMultiTable parameter. These addresses are the list of multicast addresses to which the interface is currently listening. Your endMCastAddrGet( ) must take the following form: STATUS endMCastGetAddr ( void* pCookie, MULTI_TABLE* pMultiTable ) To get the list of multicast address, use the routines provided in etherMultiLib. This function should return OK or ERROR. If an error occurs, it should set errno. The parameters are: pCookie Passes in a pointer to the END_OBJ structure you returned from your endLoad( ). pMultiTable Passes in a pointer to a buffer. This is an output parameter. Your endMCastAddrGet( ) must write a MULTI_TABLE structure into the referenced buffer. end.h defines MULTI_TABLE as follows: typedef struct { long len; /* length of table in bytes */ char *pTable; /* pointer to entries */ } MULTI_TABLE; Modify the len member of the MULTI_TABLE to indicate just how many addresses you are returning. Write the addresses to the buffer referenced in the pTable member of the MULTI_TABLE. 298
H Implementing a MUX-Based Network Interface Driver Forming an Address into a Packet for Transmission: endAddressForm( ) The endAddressForm( ) routine must take a source address and a destination address and copy the information into the data portion of the mBlk structure in a fashion appropriate to the link level. Implementing this functionality is the responsibility of the driver writer, although some common cases are provided for in endLib. After adding the addresses to mBlk, your endAddressForm( ) routine should adjust the mBlk.mBlkHdr.mLen and mBlk.mBlkHdr.mData members accordingly. This routine must take the following form: M_BLK_ID endAddressForm ( M_BLK_ID pMblk, /* packet data */ M_BLK_ID pSrcAddress, /* source address */ M_BLK_ID pDstAddress /* destination address */ ) This function returns an M_BLK_ID, which is potentially the head of a chain of mBlk structures. If the cluster referenced by pMblk does not have enough room to contain both the header and the packet data, this routine must reserve an additional mBlk/clBlk/cluster construct to contain the header. This routine must then chain the mBlk in pMblk onto the just-reserved header mBlk and returns a pointer to the header mBlk as the function value. The parameters are: pMblk The mBlk that contains the packet to be transmitted. pSrcAddress The mBlk that contains the link-level address of the source. pDstAddress The mBlk that contains the link-level address of the destination. H Getting a Data-Only mBlk: endPacketDataGet( ) This routine must provide a duplicate mBlk that contains packet data in the original but skips the header information. Some common cases are provided for in endLib. This routine should return OK or ERROR and set errno if an error occurs. 299
