Wireshark-dev: Re: [Wireshark-dev] 12 byte number

The spec describes the value as a 96-bit identifier that can range from
0 to 2^96 - 1. It serves as an id to track messages. So I think it's
just a very large unsigned number. When you say opaque value, what do
you mean by that? 

Thanks,

So it's a value to be interpreted as a nonnegative integer (so a value
of 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x02 is one
greater than a value of 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00
0x00 0x00 0x01), rather than an opaque collection of bytes or a value to
be interpreted in some fashion other than an integer?  (2^96 things is a
*lot* of things....)
