The test dose stress on the interface by running this 2 commands in loop:
command is: /sbin/ip -f inet addr add $IP/16 brd + dev ens8f1
command is: ifconfig ens8f1 $IP netmask 255.255.0.0
when $IP change every iteration.
It execute every second when we see the reproduce somewhere between 40 to 200
seconds of execution.
Thanks,
