ioprocess is misconfigured in STDCI V1 and is missing V2 configuration to be fully functional.

Currently, 4.3 is configured to come from ioprocess-1.0 branch:

 version:
      - 4.3:
          branch: ioprocess-1.0
          repoversion: 4.3

But the last commit for that branch was 12 months ago, so I assume its not being used anymore? and master branch is used for all versions?

This is why 4.3 tested repo doesn't have it and only master repo has it.

I believe you should switch to V2, it will simplify the configuration dramatically ( Ehud can help you if needed ).
