/**
 * @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.
