I think this issue, that should solve the problem of sending or delaying
packets after obtaining MLID should be solved in another patch. Proposed
code improve today situation, when you can't change it at all.
Relating to broadcast, I don't think that this is a good solution it
will bring unwarranted load, specially in the case if no MLID received.
The way of adding delay before we start to send packages, seems to me
better.
