MAC adddress routines provided by the BSP in this file are: sysNetMacNVRamAddrGet() sysNetMacAddrGet() sysNetMacAddrSet() This board provides storage in flash for the MAC addresses of the motfcc and motscc interfaces. This library also implements a RAM buffer to represent the contents of the flash. The RAM buffer contains eight entries, which is more than currently needed by this board, but can be considered as room for expansion in future boards using a derivative of this BSP. This RAM buffer is contained in the array glbEnetAddr[][]. */ #ifdef ETHERNET_MAC_HANDLER #include <vxWorks.h> #include "config.h" /* locals */ /* defines */ #ifndef MAX_MAC_DEVS #define MAX_MAC_DEVS 1 #endif #define MAC_OFFSET_MOTTSEC 0 const char *sysNetDevName[MAX_MAC_DEVS] = {"mottsec"}; /* globals */ IMPORT int dynamicMacAddrGen ( UINT8 * ifName, /* interface name */ int ifUnit, /* interface unit */ UINT8 * ifMacAddr, /* address buffer */ int ifMacAddrLen /* length of buffer */ ); /* locals */ LOCAL UINT8 glbEnetAddr[MAX_MAC_ADRS][MAC_ADRS_LEN] = { { CUST_ENET5, CUST_ENET4, CUST_ENET3_0, WR_ENET2, WR_ENET1, WR_ENET0 }, { CUST_ENET5, CUST_ENET4, CUST_ENET3_1, WR_ENET2, WR_ENET1, WR_ENET0 }, { CUST_ENET5, CUST_ENET4, CUST_ENET3_2, WR_ENET2, WR_ENET1, WR_ENET0 } }; LOCAL UINT8 sysInvalidAddr[2][MAC_ADRS_LEN] = { { 0x00, 0x00, 0x00, 0x00, 0x00, 0x00 }, { 0xff, 0xff, 0xff, 0xff, 0xff, 0xff } }; /* * To comply with 5.5.x API in bootConfig.c, sysEnetAddrSet() * doesn't take a unit number.
