* Description:
* This file provides the main() function that replaces the main function of
* wrc_main.c file when WRPC is compiled for testbench. This is done by
* wrc_main.c file when WRPC is compiled for testbench. This is done by
* configuring WRPC using make menuconfig:
* a) by using the default wrpc_sim_defconfig, i.e. "make wrpc_sim_defconfig", or
* a) by using the default wrpc_sim_defconfig, i.e. "make wrpc_sim_defconfig",or
* b) by chosing in make menuconfig the following opton:
* "Build simple software for test of WR PTP Core in simulatin"

* - checkes whether the transmitted frames are successfully received back in a proper
