51 | /* "Handles" | |
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. | |
64 | ||
65 | Macros to manipulate handles: | |
