I have a problem with initialzie Infiniband with Bluefield2.
I want to activate Host and DPU both. But It only works one side at once. Both side was activated once in seperate host mode, but DPU’s port state went down while setting network. After that It works like those pictures. Host activate infiniband interface with Separate Host mde. DPU activate infiniband interface with Embedded CPU mode.

Here are pictures of my server situation
when Separate Host mode
