* Description:
* netapp_dhcp is used to configure the network interface, static or

*
* NOTE: If the mode is altered a reset of CC3000 device is required in order

* 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
