-/* "Handles"
- ---------
-
- All the traffic control objects have 32bit identifiers, or "handles".
-
- They can be considered as opaque numbers from user API viewpoint,
- but actually they always consist of two fields: major and
- minor numbers, which are interpreted by kernel specially,
- that may be used by applications, though not recommended.
-
- F.e. qdisc handles always have minor number equal to zero,
- classes (or flows) have major equal to parent qdisc major, and
- minor uniquely identifying class inside qdisc.
-
- Macros to manipulate handles:
