Do minor editorial changes to improve documentation readability: - mark literals as such; - add table markups to hint sizes; - define what PES means; - instead of hardcoding devnode numbers to zero (like adapter0/) use a question mark, to indicate that multiple devnodes may exist; - add cross-references where useful.
