AddTimer adds a timer which may call handler function every d milliseconds It is required to add at least one variant of this timer for working TODO d should be approximate as schedTime because handler will be call from scheduler Return created timer.

SystemInit is initialization of system.

SystemInitPortsAndMemory performs all initialization necessary to create and send new packets before scheduler may be started.

SystemReset stops whole framework plus cleanup DPDK TODO DPDK cleanup is now incomplete at DPDK side It is n't able to re-init after it and also is under deprecated pragma.

SystemStart starts system - begin packet receiving and packet sending.

SystemStartScheduler starts scheduler packet processing.

SystemStop stops the system.

TODO "5" and "39" constants derived empirically.
