Approach

What is the motivation for this PR?

observed error in test_pfc_pause_extra_lossless_active:

20/07/2023 15:12:12 test_tunnel_qos_remap.pfc_pause_test     L0338 INFO   | exception (<class 'TypeError'>, TypeError("object of type 'int' has no len()"), <traceback object at 0x7fe6f02cb940>)

RCA:

the last parameter of pfc_pause_test() requrie list type, but, in some corner case,, "dualtor_meta['target_server_port']" is not list. so cause this error:

                if pfc_pause_test(storm_handler, peer_info, prio, ptfadapter, rand_selected_dut,
                                  dualtor_meta['selected_port'], queue, tunnel_pkt.exp_pkt, src_port, exp_pkt,
                                  dualtor_meta['target_server_port']):

How did you do it?

solution:
make sure the last parameter of pfc_pause_test() is list type.

How did you verify/test it?

Any platform specific information?

Supported testbed topology if it's a new test case?
