NFD

I see that "/ndn" registration is done under NFD/tools/ndn-autoconfig in base.cpp at line 96.

void
Base::registerAutoConfigNames(uint64_t faceId)
{
  static const Name TESTBED_PREFIX = "/ndn";
  registerPrefix(TESTBED_PREFIX, faceId);

  static const Name LOCALHOP_NFD_PREFIX = "/localhop/nfd";
  registerPrefix(LOCALHOP_NFD_PREFIX, faceId);
}

Should only this needs be updated or do I have to detect if a host is in consumer region first?

ndn-autoconfig is designed to run on an end host which is always consumer region, so there's no detection needed.
Base::registerAutoConfigNames and affected test cases shall be updated.

I edited the code and tested the unit-tests under build and got no errors. What should be the next step?

See NFD contributing guide for next steps.

When preparing for contribution, adding Gerrit as a remote location to my local git repo, I see that when I do git clone ssh://Ashiq@gerrit.named-data.net:29418/NFD.git , there are changes in the repo and the /ndn registration now is under tools/ndn-autoconfig/procedure.cpp file in line 40:

static const std::vector<Name> HUB_PREFIXES{"/ndn", "/localhop/nfd"};

I believe I need to modify this. Please correct me if I'm wrong

As I'm editing ndn-autoconfig manpage, I find the separation of "NDN hub discovery procedure" and "client procedure" confusing. I propose merging these two sections. What does others think?
