Fix extrapolation used in latency measurements
When doing latency measurements PROX takes into account the generation or reception of a bulk of packets. For instance, if PROX receives at time T 4 packets, it knows that the first packet was received by te NIC before T (the time to receive the other 3 packets, as they were received at maximum link speed). So the latency data is decreased by the minimum time to receive those 3 packets. For this PROX was using a default link speed of 10Gbps. This is wrong for 1Gbps and 40Gbps networks, and was causing for instance issues on 40 Gbps networks as extrapolating too much, resulting in either too low latencies or negative numbers (visible as very high latencies).
