/* CONFIG_EXAMPLES_FTPD_PRIO - Priority of the FTP daemon.
 *   Default: SCHED_PRIORITY_DEFAULT
 * CONFIG_EXAMPLES_FTPD_STACKSIZE - Stack size allocated for the
 *   FTP daemon. Default: 2048
 * CONFIG_EXAMPLES_FTPD_NONETINIT - Define to suppress configuration of the
 *   network by apps/examples/ftpd.  You would need to suppress network
 *   configuration if the network is configuration prior to running the
 *   example.
 *
 * If CONFIG_EXAMPLES_FTPD_NONETINIT is not defined, then the following may
 * be specified to customized the network configuration:
 *
 * CONFIG_EXAMPLES_FTPD_NOMAC - If the hardware has no MAC address of its
 *   own, define this =y to provide a bogus address for testing.
 * CONFIG_EXAMPLES_FTPD_IPADDR - The target IP address.  Default 10.0.0.2
 * CONFIG_EXAMPLES_FTPD_DRIPADDR - The default router address. Default
 *   10.0.0.1
 * CONFIG_EXAMPLES_FTPD_NETMASK - The network mask.  Default: 255.255.255.0
