There are three types of headers with extra 802.11 information: the RadioTap
header, the WifiExtra header and the Prism header . Each header has its
decapsulation and encapsulation elements, i.e. respectively
RadiotapEncap/Decap , ExtraEncap/Decap and Prism2Encap/Decap. So just select
the preferred header encapsulation in the driver and use the corresponding
encap/decap elements in your click script. :-)

Kind regards,
Nico
