Not really a full review, but this is apparently causing self-tests
failures:

# selftests: drivers/net: napi_id.py
# File
"/home/virtme/testing-17/tools/testing/selftests/drivers/net/./napi_id.py",
line 10
# listen_cmd = f'{cfg.test_dir / "napi_id_helper"} {cfg.addr_v['4']}
{port}'
# ^
# SyntaxError: f-string: unmatched '['
not ok 1 selftests: drivers/net: napi_id.py # exit=1

the second "'" char is closing the python format string, truncating the
cfg.addr_v['4'] expression.

Please run the self test locally before the next submission, thanks!
