 * Name: netapp_dhcp
 *
 * Description:
 *   netapp_dhcp is used to configure the network interface,  static or
 *   dynamic (DHCP).\n In order to activate DHCP mode,  aucIP, aucSubnetMask,
 *   aucDefaultGateway must be 0. The default mode of CC3000 is DHCP mode. Note
 *   that the configuration is saved in non volatile memory and thus preserved
 *   over resets.
 *
 *   NOTE: If the mode is altered a reset of CC3000 device is required in order
 *   to apply changes.\nAlso note that asynchronous event of DHCP_EVENT, which
 *   is generated when an IP address is allocated either by the DHCP server or
 *   due to static allocation is generated only upon a connection to the AP was
 *   established.
 *
 * Input Parameters:
 *   aucIP               device mac address, 6 bytes. Saved: yes
 *   aucSubnetMask       device mac address, 6 bytes. Saved: yes
 *   aucDefaultGateway   device mac address, 6 bytes. Saved: yes
