ipfilter upgrade issue

[Koen Martens]

Hi All,

Just a smallish issue with ipfilter and upgrading from 5.4 to 6-STABLE. 
The ipfilter implementation in the 6-STABLE kernel errs on the commands 
sent by the 5.4 ipf binary. This can be an issue when you are upgrading 
remotely without serial console and you have IPFILTER_DEFAULT_BLOCK 
enabled: after rebooting in the 6-STABLE kernel no firewall rules will 
be loaded and you cannot access the box anymore to make installworld..

Best,

Koen
