Every device driver’s net_dev.c

Prototype

          static void NetDev_IO_Ctrl (NET_IF     *pif,
                                      CPU_INT08U  opt,
                                      void       *p_data,
                                      NET_ERR    *perr);

Note that since every device driver’s IO_Ctrl() function is accessed only by function pointer via the device driver’s API structure, it doesn’t need to be globally available and should therefore be declared as ‘static’.
