Here default PTF log file is set to /root/ptf.log, but all tests use /tmp/.
I believe it would be better to change this default to /tmp/ as well, so we have all logs in one place.

This code is to specify where to get the PTF log and pcap files from the PTF container.

When PTF log file is not explicitly specified while calling ptf_runner.yml, PTF saves default log and pcap files to /root/ptf.log and /root/ptf.pcap on PTF container.

If explicit log file parameter is parsed from the PTF command line, this default value will be overwritten with custom log file location.

ptf_log_file_param_index: "{{ out.cmd.find('--log-file') }}"

- name: Parse custom log filename specified in PTF command
set_fact:
ptf_log_file: "{{ out.cmd[ptf_log_file_param_index|int:].split(' ')[1] }}"
when: ptf_log_file_param_index|int >= 0

- name: Set PTF pcap filename
set_fact:
ptf_pcap_file: "{{ ptf_log_file | replace('.log', '.pcap') }}"
