The various multipath tests use mausezahn to generate different flows and check how they are distributed between the available nexthops. The tool is currently invoked with an hard coded transmission delay of 1 ms. This is unnecessary when the tests are run with veth pairs and needlessly prolongs the tests. Parametrize this delay and default it to 0 us. It can be overridden using the forwarding.config file. On my system, this reduces the run time of router_multipath.sh by 93%.
