IPv6 Instability Interface Hotplug Events

Whilst running IPv6 with PBR active, there are constant events on the interfaces that triggers PBR to reload.

As a result the network stalls whilst the routing table and firewalls are rebuilt as PDR reiitialises. This can happen many times in a row or at regular sub 1 min intervals

Example...

user.notice pbr: Reloading pbr wan interface routing due to ifup of wan6

These are triggered by /etc/hotplug.d/iface/70-pbr script. I had already put a temporary exclusion in for wan6, but these events happen on all interfaces when IPv6 is enabled.

Is IPv6 stable and are interface events on IPv6 correct. the same events do no occur on IPv4 only interfaces

See: https://github.com/stangri/source.openwrt.melmac.net/issues/116

Upgrade PBR should solve that problem
