-"""This script uses T-REX stateless API to drive t-rex instance.
-
-Requirements:
-- T-REX: https://github.com/cisco-system-traffic-generator/trex-core
- - compiled and running T-REX process (eg. ./t-rex-64 -i -c 4)
- - trex_stl_lib.api library
-- Script must be executed on a node with T-REX instance
-- 2 interfaces must be configured in configuretion file /etc/trex_cfg.yaml
-
-##################### Example of /etc/trex_cfg.yaml ##########################
-- port_limit : 2 # numbers of ports to use
- version : 2
- interfaces : ["84:00.0","84:00.1"] # PCI address of interfaces
- port_info : # set eth mac addr
- - dest_mac : [0x90,0xe2,0xba,0x1f,0x97,0xd5] # port 0
- src_mac : [0x90,0xe2,0xba,0x1f,0x97,0xd4]
- - dest_mac : [0x90,0xe2,0xba,0x1f,0x97,0xd4] # port 1
- src_mac : [0x90,0xe2,0xba,0x1f,0x97,0xd5]

-Functionality:
-1. Configure traffic on running T-REX instance
-2. Clear statistics on all ports
-3. Ctart traffic with specified duration
-4. Print statistics to stdout
