> What you might be missing is the observation that the approach you're describing requires changing each and every PMD. The changes are also intrusive: need to change the ops that need the SW fall-back patching, also need to change the private data of each PMD (as assigned to the opaque dev->data->dev_private) to add the context data needed by the patched ops. Therefore, this approach is a no-go.

Can we discuss how to proceed in the technical board meeting?
