Rule one: ALWAYS include the actual traceback, rather than providing your interporetation of what it means (though you are then free to do that, too).
What makes you think it's the Match() call that's causing the problem?
I'd be willing to bet money it's the double-subscripting of Raw_packet_queue - if item [ctr] on the Raw_packet_queue isn't a list or a dict then subscripting it by [1] will give you the error message that you quote.
But if you had included the traceback you would have made it unnecessary for me to use my psychic powers :-)

I have a program in which I'm passing a list to functions. When I reference an element in a function to which it is passed, I get the error message "unsubscriptable object". When printing the list contents in that same function, I get "xxx is <Reader object at 0xyyyy>". How do I pass a list?

Earl:
It seems you code isn't optimized for debugging :-)
Why all the use of lists? I suspect (though I don;t mean to demean your programming skill) that you might be better to define object classes to represent things like the elements of your Raw_packet_queue. Then, rather than having to refer to
Raw_packet_queue[0][0][1]
you would be able to use something a little more helpful like
Raw_packet_queue[0].pkt_hdr.something
which would make the code more readable and also more writable!
Anyhow, the problem appears to be somewhere other than you originally suggested, since the code you originally posted didn't IIRC, contain any reference to Raw_packet_queue[0][0][1], while the traceback specifically points to such a reference as the cause of the problem.
If Kent Johnson is wrong about the cause of the problem then please get back to the list. And think about refactoring the code to avoid all those lists and tuples - they don't appear to be the appropriate structures for optimum readability!
