Because Linux has no analog to the registry, use this function to initialize the private adapter structure with a default configuration. One other possibility is to use a series of module parameters which can be passed in by the caller when the module is initialized. However, this implementation does not allow for seperate configurations in the event multiple devices are present, and hence will not suffice. If another method is derived which addresses this problem, this is where it should be implemented. *************************************************************************/ /************************************************************************** Set the private adapter struct with default values for the corresponding parameters *************************************************************************/ pAdapter->SpeedDuplex = PARM_SPEED_DUPLEX_DEF; pAdapter->RegistryVlanTag = PARM_VLAN_TAG_DEF; pAdapter->RegistryFlowControl = PARM_FLOW_CTL_DEF; pAdapter->RegistryWOLLink = PARM_WOL_LINK_DEF; pAdapter->RegistryWOLMatch = PARM_WOL_MATCH_DEF; pAdapter->RegistryJumboPacket = PARM_JUMBO_PKT_DEF; pAdapter->RegistryPhyComa = PARM_PHY_COMA_DEF; pAdapter->RegistryRxNumBuffers = PARM_RX_NUM_BUFS_DEF; pAdapter->RegistryRxTimeInterval = PARM_RX_TIME_INT_DEF; pAdapter->RegistryTxNumBuffers = PARM_TX_NUM_BUFS_DEF; pAdapter->RegistryTxTimeInterval = PARM_TX_TIME_INT_DEF; pAdapter->RegistryRxMemEnd = PARM_RX_MEM_END_DEF; pAdapter->RegistryMACStat = PARM_MAC_STAT_DEF; pAdapter->RegistrySCGain = PARM_SC_GAIN_DEF; pAdapter->RegistryPMWOL = PARM_PM_WOL_DEF; if( et131x_nmi_disable != PARM_NMI_DISABLE_DEF ) { pAdapter->RegistryNMIDisable = et131x_nmi_disable; } else { pAdapter->RegistryNMIDisable = PARM_NMI_DISABLE_DEF; } pAdapter->RegistryDMACache = PARM_DMA_CACHE_DEF; pAdapter->RegistryPhyLoopbk = PARM_PHY_LOOPBK_DEF; /************************************************************************** Set the MAC address to a default *************************************************************************/ memcpy( pAdapter->CurrentAddress, macAddrDef, ETH_ALEN ); pAdapter->bOverrideAddress = FALSE; DBG_TRACE( et131x_dbginfo, "Default MAC Address : %02x:%02x:%02x:%02x:%02x:%02x\n", pAdapter->CurrentAddress[0], pAdapter->CurrentAddress[1], pAdapter->CurrentAddress[2], pAdapter->CurrentAddress[3], pAdapter->CurrentAddress[4], pAdapter->CurrentAddress[5] ); /************************************************************************** Decode SpeedDuplex Set up as if we are auto negotiating always and then change if we go into force mode *************************************************************************/ pAdapter->AiForceSpeed = 0; // Auto speed pAdapter->AiForceDpx = 0; // Auto FDX /************************************************************************** If we are the 10/100 device, and gigabit is somehow requested then knock it down to 100 full. *************************************************************************/ if(( pAdapter->DeviceID == ET131X_PCI_DEVICE_ID_FAST ) && ( pAdapter->SpeedDuplex == 5 )) { pAdapter->SpeedDuplex = 4; } switch( pAdapter->SpeedDuplex ) { case 1: // 10Mb Half-Duplex pAdapter->AiForceSpeed = 10; pAdapter->AiForceDpx = 1; break; case 2: // 10Mb Full-Duplex pAdapter->AiForceSpeed = 10; pAdapter->AiForceDpx = 2; break; case 3: // 100Mb Half-Duplex pAdapter->AiForceSpeed = 100; pAdapter->AiForceDpx = 1; break; case 4: // 100Mb Full-Duplex pAdapter->AiForceSpeed = 100; pAdapter->AiForceDpx = 2; break; case 5: // 1000Mb Full-Duplex pAdapter->AiForceSpeed = 1000; pAdapter->AiForceDpx = 2; break; } DBG_LEAVE( et131x_dbginfo ); return; } /*===========================================================================*/
