[Click] Click & Wifi-Header

[John Bicket]

Hi, 

Do you see the prism headers in click?
Can you send me what you get if you run click with this command:

click -e "FromDevice(ath0) -> Print(foo, 300) -> Discard"


It may be that the prism headers have changed their format slightly, and
the current elements that parse them (like Prism2Decap()) need to be
updated.
