Actually, what is being passed is a pointer (to a pointer) to the incoming
packet (0 is the incoming request packet, 1 is the reply packet being
constructed and 2 is the result of the authentication). The ${$_[0]}
dereferences the pointer so you are manipulating the packet itself when you use
${$_[0]}->add_attr("Filter-Id", "test");
Hence any further processing of the packet will find whatever you have put
there (or changed).
