50 | /* "Handles" | |
51 | --------- | |
52 | ||
53 | All the traffic control objects have 32bit identifiers, or "handles". | |
54 | ||
55 | They can be considered as opaque numbers from user API viewpoint, | |
56 | but actually they always consist of two fields: major and | |
57 | minor numbers, which are interpreted by kernel specially, | |
58 | that may be used by applications, though not recommended. | |
59 | ||
60 | F.e. qdisc handles always have minor number equal to zero, | |
61 | classes (or flows) have major equal to parent qdisc major, and | |
62 | minor uniquely identifying class inside qdisc. | |
63 | ||
64 | Macros to manipulate handles: | |
