As far as I can tell, both patches work for me.  Your second patch is
on my production firewalls now so if anthing comes up over the
coming days I'll keep you informed.

I've tested carp, both failover to backup and fallback (preemption)
with IPv4 and with IPv6, all seems to work now.

Thannks again for your patches, hope you can get them into 8.2.
