Naresh Jayaram 13f6a07efc Add SIM identifier to the network profile and cred block
This allows the specific SIM to be identified for authentication
purposes in multi-SIM devices. This SIM number represents the index of
the SIM slot. This SIM number shall be used for the authentication using
the respective SIM for the Wi-Fi connection to the corresponding
network.
