I'm not sure yet, I've seen people ask the same thing in an other forum, but no1 answered.
I believe it is meant for virtualization. To allow a virtual machine fast/direct access to a certain piece of hardware (like a dedicated networking chip).
First of all you'd need hardware which supports isolation userspace processes to a certain piece of I/O memory (DMA).
Here is the documentation by the author:

I wonder if it could be used for something like Netmap:
