Check some more field values, and fix some tests to check against the maximum possible value given in the i4b_trace.h file rather than against that value + 1. (> max, or >= max+1, are both reasonable, but > max+1 isn't.) Check the first few packets, not just the first packet. Make some header fields unsigned, as that's how we treat them in most cases; that way we treat them that way by default.
