Diff below adds a new pointer to "struct pkthdr" to explicitly pass
some wireless nodes to the pointer without abusing the interface
pointer that I'd like to kill.
I kept and updated the comments saying that this way of passing the
corresponding node is a hack since using a dedicated pointer does
not change the design. Somebody will certainly dig into this at
some point :)
ok?
