+/**
+ * @file
+ * Application layered TCP connection API (to be used from TCPIP thread)\n
+ * This interface mimics the tcp callback API to the application while preventing
+ * direct linking (much like virtual functions).
+ * This way, an application can make use of other application layer protocols
+ * on top of TCP without knowing the details (e.g. TLS, proxy connection).
+ *
+ * This file contains the base implementation calling into tcp.
