I am doing manual testing and with ConnMan. However I would prefer to
have a global driver setting "nl80211,wext" that I can give on the
command line and that will then chosen as default if the addInterface
method doesn't give a driver. I really don't need a per interface
setting here.

Fair enough, but we are getting there and when testing, I like to be
using as much nl80211 as possible.
