-"""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: 10.10.10.0 - 10.10.10.9
- - Destination IP address range: 20.20.20.0 - 20.20.20.9
- - Source UDP port range: 1001 - 1010
- - Destination UDP port range: 2001 - 2010
- - Direction 1 --> 0:
- - Source IP address range: 20.20.20.0 - 20.20.20.9
- - Destination IP address range: 10.10.10.0 - 10.10.10.9
- - Source UDP port range: 2001-2010
- - Destination UDP port range: 1001 - 1010
