3  * Application layered TCP connection API (to be used from TCPIP thread)\n
4  * This interface mimics the tcp callback API to the application while preventing
5  * direct linking (much like virtual functions).
6  * This way, an application can make use of other application layer protocols
7  * on top of TCP without knowing the details (e.g. TLS, proxy connection).
8  *
9  * This file contains the base implementation calling into tcp.
