During various discussions this week, I decided there is an issue to decide
around the GRASP Flood message.

As it's currently defined, the node/ASA that receives a flooded objective
doesn't know where it came from; the flood relaying mechanism simply
loses the original source locator.

Is this a problem? Does the recipient of a flooded objective sometimes
need to know the source?

If so, we'd have to add a field to the Flood message. For example, we could
allow it to carry a Locator option.

BTW, flooded objectives have no lifetime - they are valid until overwritten
by a subsequent Flood message.

Comments?
