From aa97dd1ce910b839fed46ad55d1e70e403f5a930 Mon Sep 17 00:00:00 2001 From: Konstantin Ananyev Date: Tue, 21 Feb 2017 18:12:20 +0000 Subject: Introduce first version of TCP code. Supported functionality: - open/close - listen/accept/connect - send/recv In order to achieve that libtle_udp library was reworked into libtle_l4p library that supports both TCP and UDP protocols. New libtle_timer library was introduced (thanks to Cisco guys and Dave Barach for sharing their timer code with us). Sample application was also reworked significantly to support both TCP and UDP traffic handling. New UT were introduced.
