/*
 * This file contains logic to walk and print a large chunk of configuration
 * space and many of the capabilities. There are multiple sub-commands that
 * vector into the same logic (e.g. 'save-cfgspace' and 'show-cfgspace'). In
 * general, there are a few major goals with this bit of code:
 *
 *  o Every field should strive to be parsable and therefore selectable for
 *    output. This drove the idea that every field has both a short name and a
 *    human name. The short name is a dot-delineated name. When in parsable
 *    mode, the name will always refer to a single field. However, for
 *    convenience for humans, when not trying to be parsable, we show the
 *    parents in the tree. That is if you specify something like
 *    'pcie.linkcap.maxspeed', in parsable mode you'll only get that; however,
 *    in non-parsable mode, you'll get an indication of the capability and
 *    register that field was in.
 *
 *  o Related to the above, parsable mode always outputs a raw, uninterpreted
 *    value. This was done on purpose. Some fields require interpreting multiple
 *    registers to have meaning and long strings aren't always the most useful.
 *
 *  o Every field isn't always pretty printed. This was generally just a
 *    decision based upon the field itself and how much work it'd be to fit it
 *    into the framework we have. In general, the ones we're mostly guilty of
 *    doing this with are related to cases where there's a scaling value in a
 *    subsequent register. If you find yourself wanting this, feel free to add
 *    it.
 *
 *  o Currently designated vendor-specific capabilities aren't included here (or
 *    any specific vendor-specific capabilities for that matter). If they are
 *    added, they should follow the same angle of using a name to represent a
 *    sub-capability as we did with HyperTransport.
