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. | |
0f5bd7fe | 60 | |
d3678e3a YW |
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. | |
