%description:
Testing Ethernet communication on EtherHub with 100MBps, with disconnecting and reconnecting some hosts.
Simulation has 5 pairs of hosts that communicate with each other.
All hosts use EtherMAC implementation with half duplex mode.
All hosts have same ethernet configurations.
All hosts send requests and also reply to requests sent to them.

checks:
 - the idle state of rx is less than or equals to 6.5% in all hosts
 - the utilization state of rx is more than or equals to 93% in all hosts
