[ Test case ]

Install iptables-netflow-dkms:

$ sudo apt install iptables-netflow-dkms

Load the module:

$ sudo modprobe ipt_NETFLOW

[ Fix ]

Linux 6.11 does not allow to have empty elements
at the end of the ctl_table arrays (sentinels) anymore.
Therefore it is necessary to adjust the code accordingly.

[ Regression potential ]

We may experience networking-related regressions in systems that are
using the iptables-netflow-dkms module.
