This initialization occurs after a sufficient about of the OS has been initialized so that driver registration can be performed, but before the completion of OS initialization and before the first application is started. In a few situations, however, you may want to suppress this early network driver initialization. As examples: - If you are using SLIP or PPPD, then there will be no network driver to be initialized, - Certain multi-network configurations where a simple call to up_netinitialize() may be insufficient, and - Situations where there are other board-level hardware dependencies so that the hardware is not in an appropriate state for up_netinitialize() to be called. Examples of this latter situation includes such things as network drivers that required some setup via an I2C I/O expander, or network drivers that depend on USB, SPI, I2C, PCI, serial, or other interfaces that may not be ready when up_netiniailize() is normally called. config NET_DUMPPACKET bool "Enable packet dumping" depends on DEBUG_FEATURES default n ---help--- Some Ethernet MAC drivers supporting dumping of received and transmitted packets as a debug option.
