* \file net_nvm_api.h
* \brief Library PANA NVM API for Client and Server.
*
* \section server-api Server NVM API
*
* PANA server security material is crypted always and if you change the border router RF module
* decrypt does not work properly.
*
* - pana_server_nvm_callback_set(), Initialize PANA server NVM functionality.
* - pana_server_restore_from_nvm(), Load crypted PANA server base and security material from NVM.
* - pana_server_nvm_client_session_load(), Load crypted client session from NVM.
*
* \section client-api Client NVM API
*
* nw_nvm.c use already this API and the application can just use net_nvm_api.h.
*
* - pana_client_nvm_callback_set(), Initialize PANA session NVM.
* - net_read_persistent_data(), Read NWK ID & MAC 16-bit address.
* - net_nvm_data_load(), Load PANA session, NWK-ID and short address to stack for re-use.
* - net_pana_client_session_nvm_data_load(), Load saved PANA session with specific address or not.
