| 50 | --------- |
| 51 | |
| 52 | All the traffic control objects have 32bit identifiers, or "handles". |
| 53 | |
| 54 | They can be considered as opaque numbers from user API viewpoint, |
| 55 | but actually they always consist of two fields: major and |
| 56 | minor numbers, which are interpreted by kernel specially, |
| 57 | that may be used by applications, though not recommended. |
| 58 | |
| 59 | F.e. qdisc handles always have minor number equal to zero, |
| 60 | classes (or flows) have major equal to parent qdisc major, and |
| 61 | minor uniquely identifying class inside qdisc. |
