WE private interface was a big mess and we are still suffering from
it. Adding an interface like that will basically ruin any clean API we

For example, it has been a basic design decision in nl80211 to not
have any private interfaces. The only exception is the testmode
command, but that's only for very low level hardware specific test and
calibration commands. It should not be used in any normal operations.

And then nobody has any incentive to implement proper interfaces and
we are stuck with driver specific private interfaces, again. Please,
let's not do the same mistakes again.
