"""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 / DOT1Q / IP /
 - Direction 0 --> 1:
   - VLAN range:                    1 - 10
   - Source IP address range:       10.0.0.1 - 10.0.0.254
   - Destination IP address range:  20.0.0.1 - 20.0.0.254
 - Direction 1 --> 0:
   - VLAN range:                    1 - 10
   - Source IP address range:       20.0.0.1 - 20.0.0.254
   - Destination IP address range:  10.0.0.1 - 10.0.0.254
