I investigated the failure on the RHEL 10 ppc64le test system.


The netfilter_pkt failure is due to missing userspace dependencies:

Can't exec "nc": No such file or directory
Can't exec "iptables": No such file or directory
Can't exec "ip6tables": No such file or directory

I checked the system and confirmed that nc, ncat, iptables, and 
ip6tables are not installed:


which nc
which ncat
which iptables
which ip6tables


all return "not found".

The system has nftables installed (/usr/sbin/nft), but I was unable to 
locate packages providing nc/ncat or iptables/ip6tables in the currently 
enabled repositories (epel, rh10_base, rh10_app, rh10_crb).


At this point, the remaining failure appears to be an environmental 
dependency issue rather than a test failure. Please let me know if there 
is a recommended package/repository for EL10 ppc64le that provides 
netcat and iptables compatibility tools, and I can re-run the test.

Venkat.
