#define RAPIDIO_V4_INTERFACE "rapidio_v4"

This interface is designed for peer-to-peer RapidIO communication. It supersedes the rapidio_v3 interface; the only significant change is the use of response functions instead of return values, which makes it possible to use the interface over a link where communication is not instantaneous.

The rapidio_v4 interface has been superseded by rapidio_v5. Please see rapidio_v5 for more details.
