About NDI interface support in WinOF

Hi, all.
I’m working on Windows RDMA programming(suppose supporting both roce and infiniband),
I see that from WinOF-2, only Microsoft’s Network Direct Interface is supported, I would like to ask
a few related questions as belowing:

  1. Does ibverbs interface will no longer be supported in the future under windows platform ?
  2. Can we support RDMA transport between different platforms in runtime by programming, say linux and windows, that QPs connecting between one linux system and another windows system ?
  3. Why windows NDI interface programming must need a provider IP address ? we know that Infiniband do not need an actuall IP address.
