QUIC/inet/tests/statistical/EtherMACs_compare_twohosts_speed.test

%description:
Testing Ethernet communication from a source host to a sink host on full duplex gigabit ethernet connection.
The hosts have same ethernet configurations in pairs.

variations:
 - queue: internal / external
 - implementation: EtherMAC / EtherMACFullDuplex

compare results of variations and checks:
 - the number of sent packets are equals (one packet different is acceptable, because the first event of endtime is processed.)
 - the idle state of rx is smaller or equals than 2% in all sink hosts
 - the utilization state of rx is more tan or equals to 98% in all sink hosts
