We sometimes observe failures in the test due to too large discrepancy
between the measured and expected ratios. For example:
TEST: ECMP [FAIL]
Too large discrepancy between expected and measured ratios
INFO: Expected ratio 1.00 Measured ratio 1.11
Fix this by allowing an up to 15% deviation between both ratios.
Another possibility is to increase the number of generated flows, but
this will prolong the execution time of the test, which is already quite
high.
