Hi,

I converted my old conf file using config_converter.py but there is no
Nvme section in the json file output. When I run nvmf_tgt I get these
errors.

[2021-01-11 20:41:39.448690] json_config.c:
392:app_json_config_load_subsystem_config_entry: *DEBUG*: 	params: {

Not sure why there is an iscsi_set_options method in my json.  This is the
nvme section in the conf file:

[Nvme]
  TransportId "trtype:PCIe traddr:0007:01:00.0" Nvme0
  HotplugEnable Yes
  HotplugPollRate 1000000

And my json is below. Is there something missing in it?
