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

118 | For usual devices it is equal ifi_index. | |

120 | can point to real physical interface (f.e. for bandwidth calculations), | |
121 | or maybe 0, what means, that real media is unknown (usual | |
122 | for IPIP tunnels, when route to endpoint is allowed to change) | |
