I mainly focussed on reworking brcmfmac to support multiple (virtual) 
interfaces and wireless devices without netdev. So far I only did the 
scanning part of p2p device discovery which is a regular 802.11 scan so 
no API change needed there. So no API change proposals yet. When I learn 
more I will discuss it on the wireless list.
