Change subject: ifcfg: re-enable IPv6 before device configuration, or disable 
afterwards
......................................................................


Patch Set 5:

On enabling/disabling IPv6 in the whole hierarchy: you can remember we had 
success pinging a bridge's IPv6 link-local address from a VM.

So maybe it is possible to ping e.g. a VLAN's LL address as well.

No service would likely be running there but if it were possible to communicate 
over IPv6 we should like to disable it altogether.

For now, it just looks cleaner to me when all the devices don't have their ugly 
LL addresses when the top level didn't ask for IPv6, and similarly, that they 
all do when it asked.

If there IS really a complication when the whole hierarchy is disabled, I 
should think about VLANs which share a NIC, and not disable IPv6 on the NIC.
