+ * @brief Implementation of the compatibility layer.
+ *
+ * The structure of the core API has evolved to support operations of a variety
+ * of packet formats in addition to IPv4/TCP and IPv6/TCP, namely with the use
+ * of ICMP for signalization and AH headers for integrity. The new API format
+ * has been designed to scale better with the multiplicity of packet formats,
+ * and provide a unified interface on top. We maintain an interface for the
+ * former API in this file, which mainly acts as a wrapper on top of new calls.
