| 89 | The only change is: |
| 90 | IFF_LOOPBACK, IFF_BROADCAST and IFF_POINTOPOINT are |
| 91 | more not changeable by user. They describe link media |
| 92 | characteristics and set by device driver. |
| 93 | |
| 94 | Comments: |
| 95 | - Combination IFF_BROADCAST|IFF_POINTOPOINT is invalid |
| 96 | - If neither of these three flags are set; |
| 97 | the interface is NBMA. |
| 98 | |
| 99 | - IFF_MULTICAST does not mean anything special: |
| 100 | multicasts can be used on all not-NBMA links. |
| 101 | IFF_MULTICAST means that this media uses special encapsulation |
| 102 | for multicast frames. Apparently, all IFF_POINTOPOINT and |
| 103 | IFF_BROADCAST devices are able to use multicasts too. |
