Bug 2727

examples/wireless/examples-to-run.py lists

vht-wifi-network --simulationTime=0.1 --minExpectedThroughput=5 --maxExpectedThroughput=555

However, highest data rate is 866.7 for VHT MCS 9 with short guard interval.

It is easy to get throughput higher than 555:

I am changing some code in Wi-Fi initialization now and assigned streams are a bit different, so I get different throughput and test fails.

How about increasing maxExpectedThroughput to 866.7? Maybe some overhead should be taken into account, but maxExpectedThroughput should be some theoretically computed upper bound, not just some value slightly above the one developer got when he ran an example.
