49 | /* "Handles" | |
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. | |
62 | ||
63 | Macros to manipulate handles: | |
