Normally, up_netinitialize + * is defined in board/up_network.c for board-specific ethernet + * implementations, or chip/xyx_ethernet.c for chip-specific ethernet + * implementations. The stub version here is used in the cornercase where + * the network is enable yet there is no ethernet driver to be initialized. + * In this case, up_initialize will still try to call up_netinitialize() + * when one does not exist. This cornercase would occur if, for example, + * only a USB network interface is being used or perhaps if a SLIP is + * being used). + * + * In the long run, it might be better to have some kind of CONFIG_NO_ETHERNET + * to suppress the call to up_netinitialize() in up_initialize(). Then + * this stub would not be needed. + * + ****************************************************************************/ + +void up_netinitialize(void) +{ +} |
