508 + ---------
509 +
510 + All the traffic control objects have 32bit identifiers, or "handles".
511 +
512 + They can be considered as opaque numbers from user API viewpoint,
513 + but actually they always consist of two fields: major and
514 + minor numbers, which are interpreted by kernel specially,
515 + that may be used by applications, though not recommended.
516 +
517 + F.e. qdisc handles always have minor number equal to zero,
518 + classes (or flows) have major equal to parent qdisc major, and
519 + minor uniquely identifying class inside qdisc.
520 +
