[Click] Click and Wireless Tools

[Douglas S. J. De Couto]

Hi Peter,

You can put any code you like in an element.  However, if it calls a 
userlevel library, it will only run in userlevel click, and needs to 
have ELEMENT_REQUIRES(userlevel) at the end of the element code.  
Similarly, if it relies on kernel code, it will only run in kernel 
click.

We have some elements that tightly integrate with wireless devices in 
the kernel, but the do require patching the device drivers and kernel 
in some cases; see the elements in in elements/wifi, especially 
WifiTXFeedback. It would be great if there were some elements that 
talked to the more general wireless library.
