Chalk this up to being easily confused by a flood of data. The packet sizes happened to be awfully close to standard header sizes, and I just wasn't thinking. Everything checks out with the header sizes. And with a little adjustment to the code I was using to parse some of the packet data, I am now seeing everything I expect to.
