Field Documentation

uint8_t _CONFNET::cd_size

Size of this structure.

Used by Nut/Net to verify, that the structure contents is valid after reading it from non-volatile memory.

Definition at line 114 of file confnet.h.

Referenced by AsixInit(), cs8900Init(), CSNicInit(), NicInit(), NutNetLoadConfig(), and NutNetSaveConfig().

char _CONFNET::cd_name[9]

Magic cookie.

Contains the device name of the network interface.

Examples:: editconf/editconf.c.

Definition at line 120 of file confnet.h.

Referenced by AsixInit(), main(), NutNetIfSetup(), and NutNetLoadConfig().

uint8_t _CONFNET::cdn_mac[6]

Ethernet MAC address.

Unique Ethernet address of the network interface.

Examples:: editconf/editconf.c.

Definition at line 126 of file confnet.h.

Referenced by AsixInit(), cs8900Init(), CSNicInit(), DiscoveryResponder(), main(), NicInit(), NutDhcpIfConfig(), NutDiscoveryAnnTele(), NutDiscoveryAppConf(), NutNetIfSetup(), and NutNetLoadConfig().

uint32_t _CONFNET::cdn_ip_addr

Last used IP address.

Each time Nut/Net receives an IP address during boot, it will store the address in here.

If no fixed IP address has been configured (cdn_cip_addr contains 0.0.0.0) and if no DHCP server is available, then Nut/Net will use this one, if it is not 0.0.0.0.
