Well, this particular bug rather looks like a potential documentation
insufficiency:

Instantiating two user space networking stacks on the _same_ vlan with
_identical_ parameters is just asking for troubles. If the reporter read
the manual and then did the mistake, we may have to clarify the docs
what "-net user" does.

IMHO so far nothing - as long as the ratio of pure downstream issues
remains low. I think we should give this channel a chance as it can be
advantageous to have more "real" end-user reports.
