The ethtool_rmon.sh script checks that the number of packets sent / received during a test matches the expected value with a 1% tolerance.
Since in the next patches this test will gain the capability to also be run on systems with a single interface where the traffic generator is accesible through ssh, use the UINT32_MAX as the upper limit. This is necessary since the same interface will be used also for control traffic (the ssh commands) as well as the mausezahn generated one.
