Concatenation issue in tests/common/helpers/pfc_gen_t2.py

[harsgoll]

While running PFCWD test cases, encountered concatenation issue on sonic fanout.

root@xx37-root-fanout:/tmp# sudo nice --20 python pfc_gen_t2.py -p 16 -t 65535 -s 8 -n 1000000 -i Ethernet152 -r 1.76.0.62
Traceback (most recent call last):
File "/tmp/pfc_gen_t2.py", line 340, in
main()
File "/tmp/pfc_gen_t2.py", line 264, in main
fo_logger.debug(fo_str + ' sendmmsg got errno ' + str(errno) + ' for socket ' + s.getsockname())
TypeError: can only concatenate str (not "tuple") to str

We converted s.getsockname() into str and able to proceed further.
