93 | /* ifi_flags. |
94 | ||
95 | IFF_* flags. | |
96 | ||
97 | The only change is: | |
98 | IFF_LOOPBACK, IFF_BROADCAST and IFF_POINTOPOINT are | |
99 | more not changeable by user. They describe link media | |
100 | characteristics and set by device driver. | |
101 | ||
102 | Comments: | |
103 | - Combination IFF_BROADCAST|IFF_POINTOPOINT is invalid | |
104 | - If neither of these three flags are set; | |
105 | the interface is NBMA. | |
106 | ||
107 | - IFF_MULTICAST does not mean anything special: | |
108 | multicasts can be used on all not-NBMA links. | |
109 | IFF_MULTICAST means that this media uses special encapsulation | |
110 | for multicast frames. Apparently, all IFF_POINTOPOINT and | |
111 | IFF_BROADCAST devices are able to use multicasts too. | |

114 | /* IFLA_LINK. | |
115 | For usual devices it is equal ifi_index. | |
116 | If it is a "virtual interface" (f.e. tunnel), ifi_link | |
117 | can point to real physical interface (f.e. for bandwidth calculations), | |
118 | or maybe 0, what means, that real media is unknown (usual | |
119 | for IPIP tunnels, when route to endpoint is allowed to change) | |
