IPv6 routes parsing bug on 2.6.0 #4541
Description
Brief description
After upgrading to scapy 2.6 previously working scripts now fail at the import stage. I've been able to reproduce this on the command line in a venv with only scapy installed.
I've attached a full version of the stack trace
example.txt
I've noticed from the stack trace reference to inet6. inet6 is not enabled on this host
$ ip a | grep inet6
$
Scapy version
2.6.0
Python version
3.9
Operating system
Linux 4.18.0-372.26.1.el8_6.x86_64
Additional environment information
Using rockylinux8
How to reproduce
using python3.9 run the following
from scapy.all import *
Actual result
(venv) myhost:~/username/project$ python
Python 3.9.18 (main, Nov 18 2023, 01:00:14)
[GCC 8.5.0 20210514 (Red Hat 8.5.0-20)] on linux
