>Organization:
The NetBSD Foundation, Inc.
>Environment:
System: NetBSD night-owl.duskware.de 6.99.17 NetBSD 6.99.17 (NIGHT-OWL) #142: Thu Mar 14 21:40:50 CET 2013 martin@night-owl.duskware.de:/usr/src/sys/arch/amd64/compile/NIGHT-OWL amd64
Architecture: x86_64
Machine: amd64
>Description:

IPF inconsistently uses different union fiels, which happen to overlay
to the same storage on some archs but do not align as expected on others.
One example are nat->nat_osport and nat->nat_nicmpid.

>How-To-Repeat:
Code inspection.

>Fix:
Darren tracks this upstream already - hope he will have some soon.

 Log Message:
 Mark a few more test cases known to only work by chance as failing
 and point to PR 47665.
 Julio: how do we make such cases not fail when they actually happen to
 work (by pure luck)?

 Log Message:
 PR kern/47665
 For ICMP packets, use the "oicmpid" and "nicmpid" fields explicitly rather
 than overloading those with "port" in them and expecting them to work.
