Yes the existing Monitor Mode Try #13 is fine for me and the userland
projects I know about, but actually I quite liked your encapsulation
thing -- in itself is compatible with working in any mode.  The only
problem with it right now is that it seems when mananged mode interfaces
 are not associated, they are in a netif_carrier_off() state or similar.
 If in the future it becomes possible to via netlink to target types of
packets to come down any interface in encapsulated bubbles, then
possibly it makes sense to use the encapsulated version.  But of course
either way will be great compared to nothing.
