When we run traffic_replay, we are creating millions of Packet objects.
So small change in Packet.__init__ will make big difference.
By initializing packet with converted values without parsing string, the time
cost for 3961148 calls of Packet.__init__ dcrease from 17s to 4s, according
to cProfile.

> If the level is 102 or 502, the Windows implementation checks whether
