"""Stream profile for T-rex traffic generator.

Stream profile:
 - Two streams sent in directions 0 --> 1 and 1 --> 0 at the same time.
 - Packet: ETH / IP /
 - Direction 0 --> 1:
   - Source MAC address range:      ca:fe:00:00:00:00 - ca:fe:00:07:a1:1f
   - Destination MAC address range: fa:ce:00:00:00:00 - fa:ce:00:07:a1:1f
   - Source IP address range:       10.0.0.0 - 10.7.161.31
   - Destination IP address range:  20.0.0.0 - 20.7.161.31
 - Direction 1 --> 0:
   - Source MAC address range:      fa:ce:00:00:00:00 - fa:ce:00:07:a1:1f
   - Destination MAC address range: ca:fe:00:00:00:00 - ca:fe:00:07:a1:1f
   - Source IP address range:       20.0.0.0 - 20.7.161.31
