%description:
Tests Ethernet communication via switch.
All hosts use EtherMAC implementation with external queue.
Simulation has pairs of hosts that communicate with each other via only one switch.
Both hosts in pair have same ethernet configurations.
Both hosts in pair are source and sink, too.

variations:
 - speed: 10Mbps / 100Mbps / 1000Mbps

checks:
 - the idle state of rx is less than or equals to 2% in all hosts
 - the utilization state of rx is more than or equals to 98% in all hosts
