Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

Comments:

- Combination IFF_BROADCAST|IFF_POINTOPOINT is invalid

- If neither of these three flags are set;

the interface is NBMA.
|

|

- IFF_MULTICAST does not mean anything special:
|
||||
multicasts can be used on all not-NBMA links.
|
||||
IFF_MULTICAST means that this media uses special encapsulation
|
||||
for multicast frames. Apparently, all IFF_POINTOPOINT and
|
||||
IFF_BROADCAST devices are able to use multicasts too.
