* Description :
*
* This API defines structs, formats and enums for all perftest benchmarks.
* It includes parameters parser, and a report generator.
*
* Methods :
*
* link_layer_str - Return a String representation of the link type.
* parser - Setting default test parameters and parsing the user choices.
* check_link - Configures test MTU,inline and link layer of the test.
* check_link_and_mtu - Configures test MTU,inline and link layer of the test.
* print_report_bw - Calculate the peak and average throughput of the BW test.
* print_full_bw_report - Print the peak and average throughput of the BW test.
* print_report_lat - Print the min/max/median latency samples taken from a latency test.
* print_report_lat_duration - Prints only the avergae latency for samples taken from
* a latency test with Duration..
* set_mtu - set MTU from the port or user.
* set_eth_mtu - set MTU for Raw Ethernet tests.
