Callback to get the Wi-Fi status update.

Parameters

[in]	u8MsgType	type of Wi-Fi notification. Possible types are: M2M_WIFI_RESP_CURRENT_RSSI M2M_WIFI_RESP_CON_STATE_CHANGED M2M_WIFI_REQ_DHCP_CONF
[in]	pvMsg	A pointer to a buffer containing the notification parameters (if any). It should be casted to the correct data type corresponding to the notification type.
