- I'm not sure it's the correct way to fix
it. Having mgb_pull return
a pointer to the end of the bytes we just removed seems a very weird
API ... maybe the bug is msgb_pull itself.
Ok, I guess changing the api of pull wouldn't be a great idea because
of other users and symmetry to _put ...
But then, I would introduce a msgb_pull_buffer() or _data that
returns a pointer to the buffer/data zone that's just been pulled.
Cheers,
