Svp wat preciezer aangeven, ik denk dat de tb dit doet (?):
Purpose: Test statistics offload Description: The eth_statistics is used to verify that the correct number of packets is received. The contents and size of the packets is not verified.Edited by Eric Kooistra changed this line in version 5 of the diff

100 ms lijkt mij veel te lang voor simulatie, c_nof_block_per_sync = 16 dus een sync interval duur 1024 * 16 * 5 ns = 81.92 us, dus een timeout van 100 us zou al genoeg moeten zijn om de simulatie af te latren breken door eth_statistics. Svp in comment aangeven waarom je de timeout op een bepaalde waarde zet.
