VxWorks 5.5 <strong>BSP</strong> Developer’s <strong>Guide</strong> this driver. Your driver uses this function pointer to pass data up to the protocol. attached A BOOL indicating whether or not the device is attached. The MUX sets and manages this value. txSem A semaphore that controls access to this device’s transmission facilities. The MUX sets and manages this value. flags A value constructed from ORing in IFF_* flag constants. Except for IFF_LOAN and IFF_SCAT, these constants are the same IFF_* flags associated with the TCP/IP stack. IFF_UP IFF_BROADCAST IFF_DEBUG IFF_LOOPBACK IFF_POINTOPOINT IFF_NOTRAILERS IFF_RUNNING IFF_NOARP IFF_PROMISC IFF_ALLMULTI IFF_OACTIVE IFF_SIMPLEX IFF_LINK0 IFF_LINK1 IFF_LINK2 IFF_MULTICAST IFF_LOAN IFF_SCAT The interface driver is up. The broadcast address is valid. Debugging is on. This is a loopback net. The interface is a point-to-point link. The device must avoid using trailers. The device has successfully allocated needed resources. There is no address resolution protocol. This device receives all packets. n This device receives all multicast packets. Transmission in progress. The device cannot hear its own transmissions. A per link layer defined bit. A per link layer defined bit. A per link layer defined bit. The device supports multicast. The device supports buffer loaning. The device supports scatter/gather. pFuncTable A pointer to a net_funcs structure. This structure contains function pointers to your driver’s entry points for handling standard requests such as unload or send. Your driver must allocate and initialize this structure when the device is loaded. See Identifying the Entry Points into Your Network Driver: NET_FUNCS, p.286. 284
H Implementing a MUX-Based Network Interface Driver mib2Tbl An M2_INTERFACETBL structure for tracking the MIB-II variables used in your driver. Your driver must initialize the structure referenced here, although both your driver and the MUX will later adjust the values stored in the table. NOTE: The mib2Tbl field is retained for backwards compatibility with RFC 1213. It is not recommended for new drivers. For new drivers, use the RFC 2233 interface. For more information, see H.7 Converting an END Driver from RFC 1213 to RFC 2233, p.311. pAddrList A pointer to the head of a list of multicast addresses. The MUX sets and manages this list, but it uses your driver’s endMCastAddrAdd( ), endMCastAddrDel( ), and endMCastAddrGet( ) entry points to do so. nMulti A value indicating the number of addresses on the list referenced in the multiList member. The MUX sets this value using the information returned by your driver’s endMCastAddrGet( ). protocols The head of the list of protocols that have bound themselves to this network driver. The MUX manages this list. snarfProto A BOOL indicating whether a packet-snarfing protocol has bound itself to this driver. Such a protocol can prevent the packet from passing on to lower priority protocols (see Snarfing Protocols Block Packets to Lower Priority Protocols, p.302). The MUX sets and manages this value. pMemPool A pointer to a netBufLib-managed memory pool. The MUX sets the value of this member. Treat it as opaque. pMib2Tbl The interface table for RFC 2233 compliance. H Tracking Your Device’s Control Structure: DEV_OBJ Your driver uses the DEV_OBJ structure to tell the MUX the name of your device and to hand the MUX a pointer to your device’s control structure. This control structure is a device-specific structure that you define according to your needs. Your driver uses this control structure to track things such as flags, memory pool 285
