* 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
* aucDNSServer device mac address, 6 bytes. Saved: yes
