VxWorks 5.5 <strong>BSP</strong> Developer’s <strong>Guide</strong> Step 1: Modify the END load routine to set up the RFC 2233-type MIB in the END_OBJ. In the xxxEndLoad( ) routine, initialize the MIB-II entries (for RFC 2233). For example: pDrvCtrl->endObj.pMib2Tbl = m2IfAlloc(M2_ifType_ethernet_csmacd, (UINT8*) enetAddr, 6, ETHERMTU, speed, DEV_NAME, pDrvCtrl->unit); if (pDrvCtrl->endObj.pMib2Tbl == NULL) { logMsg ("%s%d - MIB-II initializations failed\n", DEV_NAME, pDrvCtrl->unit,0,0,0,0); goto errorExit; } /* * Set the RFC2233 flag bit in the END object flags field and * install the counter update routines. */ m2IfPktCountRtnInstall(pDrvCtrl->endObj.pMib2Tbl, m2If8023PacketCount); /* * Make a copy of the data in the mib2Tbl struct as well. We do this * mainly for backward compatibility issues. There might be some * code that references the END pointer and does lookups on the mib2Tbl, * which causes all sorts of problems. */ bcopy ((char *)&pDrvCtrl->endObj.pMib2Tbl->m2Data.mibIfTbl, (char *)&pDrvCtrl->endObj.mib2Tbl, sizeof (M2_INTERFACETBL));/* Mark the device ready */ END_OBJ_READY (&pDrvCtrl->endObj, IFF_NOTRAILERS | IFF_MULTICAST | IFF_BROADCAST | END_MIB_2233); Step 2: Modify the END unload routine to delete the RFC 2233-type MIB from the END_OBJ. In the xxxEndUnload( ) routine, add MIB-II free routine entries. For example: m2IfFree(pDrvCtrl->endObj.pMib2Tbl); pDrvCtrl->endObj.pMib2Tbl = NULL; Step 3: Change the hardware address macro to point to the new location of the physical address. The hardware address macro is usually defined with the name END_HADDR(pEnd) but may be defined with the prefix reflecting the actual driver, such as in the fei82557End driver, where it is FEI_HADDR(pEnd). 312
H Implementing a MUX-Based Network Interface Driver Set the hardware address macro to point to where the physical address is stored in the RFC 2233-type MIB. For RFC 2233-type MIBs, the physical address for an Ethernet device is stored in the pMib2Tbl in the END_OBJ. For example: #define END_HADDR(pEnd) \ ((pEnd)->pMib2Tbl->m2Data.mibIfTbl.ifPhysAddress.phyAddress) Step 4: Add the EIOCGMIB2233 case in the ioctl routine. For example: /* New RFC 2233 mib2 interface */ case EIOCGMIB2233: if ((data == NULL) || (pEndObj->pMib2Tbl == NULL)) error = EINVAL; else *((M2_ID **)data) = pEndObj->pMib2Tbl; break; Step 5: Replace the old RFC 1213 interface API with the RFC 2233 interface API; then delete the old RFC 1213 interface API. RFC 1213 interface API. The old RFC 1213 interface used the END_ERR_ADD macro for both updating packet counts and for counting error conditions. (a) Replace all instances of END_ERR_ADD calls. After an END_ERR_ADD instance is replaced, it can be deleted. For example: END_ERR_ADD (&pDrvCtrl->endObj, MIB2_IN_UCAST, +1); (b) Replace the deleted RFC 1213 interface. H RFC 2233 Interface API. The RFC 2233 interface API consists of m2IfGenericPacketCount( ) and m2IfCounterUpdate( ). These routines are accessed through pointers stored in pMib2Tbl of the END_OBJ. The pointer to m2IfGenericPacketCount( ) is held in pDrvCtrl-> endObj.pMib2Tbl-> m2PktCountRtn. The pointer to m2IfCounterUpdate( ) is in pDrvCtrl-> endObj.pMib2Tbl-> m2CtrUpdateRtn. The APIs for these routines are as follows: m2If8023PacketCount. Increment the interface packet counters for an 802.3 device. This function is used to update basic interface counters for a packet. The ctrl argument specifies whether the packet is being sent or received (M2_PACKET_IN or M2_PACKET_OUT). This function works for the 802.3 313
