<p class="MsoNormal">I don’t have access to the Intel GitHub any longer – can you provide the commit ID. I agree we need to unravel the dependencies on the StarlingX code base in this case. Let’s see which bits can be separated. Can you please clarify the
dependency you are identifying?<o:p></o:p></p>

<p class="MsoNormal">Which of these commits have dependencies on StarlingX code?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I think the Provider network management will need some socialization with the community and be able to stand alone. This simplifies network configuration, which is a very nice usability feature.
