There is definitely interest since Qualcomm is also working on an RFC for this
functionality. You can wait for our proposal, or publish your own.
In addition, Qualcomm is working on an RFC for supporting per-radio attributes
via get/set wiphy for drivers that support multi-radio wiphys.
We hope to have these RFCs out next week...
