| --------- |
| |
| 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. |
