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