Just a quick look at the format of the code I notice a number of places missing a blank line after the declarations in a function e.g. dsw_xstats_port_get() an others. Just to help when you send this in as a real patch. Make sure you run checkpatch.

As for the RFC I like the idea of this RFC, but need to dig into the code.

Thanks
