If the values are:
	p->dev == NULL
	ifindex == 0
	p->net != net

The parms should not be taken into account and the looping must 
continue. But with this modification it is not the case, if we specify 
parms ifindex == 0, the first parms with the dev field set to NULL will 
be taken belonging or not to the right net.

They should be taken. In the other case inetdev_event will fail for sure
in the middle. You could check.

These are ARP defaults and I do not see a problem for now to get them.

Because there is a parms default per namespace. So several instances of 
them per nd table. That was the initial approach with Eric's patchset.
