Hello World not working as expected

[moscovium115]

Hi, I'm trying to use the Hello world example of F-stack since another library depends on this. After the installation proces on Amazon Linux (so this was attempted on AWS EC2) I saw the following when running Hello world:

f-stack-0: No addr6 config found.
f-stack-0: Ethernet address: 0a:2a:f3:8c:ab:a5

Maybe something is wrong with my installation process? Amazon Linux is not my preferred platform but the guide https://github.com/F-Stack/f-stack/blob/dev/doc/Launch_F-Stack_on_AWS_EC2_in_one_minute.md was tailored for that platform. Since im running on the cloud, I didn't want to sacrifice the only NIC on my machine. So I added another one which is called ens6 (using ENA)

I install in the following way:

sudo su

sudo yum install -y git gcc openssl-devel kernel-devel-$(uname -r) bc numactl-devel make cmake net-tools vim pciutils iproute pcre-devel zlib-devel elfutils-libelf-devel meson python3-pip

mkdir data
cd data
mkdir f-stack

pip3 install pyelftools --upgrade

git clone https://github.com/F-Stack/f-stack.git /root/data/f-stack

cd /root/data/f-stack/dpdk

Never Mind, after some more testing i dont think its the fault of F-stack but of the library
