It's complicated. The interface has radiotap+802.11 type, so on the one
hand it should have 802.11 header. On the other hand, having what went
to the hardware can be helpful. However, I don't think we can get
around the radiotap+802.11 type in any way.

Well I think it's something we should consider when we look at this
path. Hopefully nobody who really cares about performance has the
monitor stuff active - although we're thinking of ways to push down
filters to make that less expensive.
