"""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 / UDP
 - Direction 0 --> 1:
   - Source IP address range:      20.0.0.0
   - Destination IP address range: 12.0.0.2
   - Source UDP port range:        1024 - 1038
   - Destination UDP port range:   1024
 - Direction 1 --> 0:
   - Source IP address range:      12.0.0.2
   - Destination IP address range: 200.0.0.0
   - Source UDP port range:        1024
   - Destination UDP port range:   1024 - 1038
