Using nftables on a Windows WSL machine doesn't work

[l0rd]

Issue Description

After updating to Fedora 41 and configuring the machine in rootful mode, running a container returns a netavark error:

# podman run hello
WARN[0000] Using cgroups-v1 which is deprecated in favor of cgroups-v2 with Podman v5 and will be removed in a future version. Set environment variable `PODMAN_IGNORE_CGROUPSV1_WARNING` to hide this warning.
internal:0:0-0: Error: Could not process rule: No such file or directory

internal:0:0-0: Error: Could not process rule: No such file or directory

Error: netavark: nftables error: nft did not return successfully while applying ruleset

Steps to reproduce the issue

Steps to reproduce the issue

1. Build a WSL image based on Fedora 41 (for testing, I have built and pushed one to quay.io/mloriedo/machine-os-wsl:5.5-next)
2. Init/Run a rootful machine using the Fedora 41 based image:

> podman machine init --image docker://quay.io/mloriedo/machine-os-wsl:5.5-next
> podman machine set --rootful
> podman machine start
> podman run hello

podman info output

Podman built from main branch running on Windows 11 with WSL v2.4.9.0 and Kernel v5.15.167.4-1

Additional information

Using a more recent version of the Kernel (v6.6.36) doesn't help.

Configuring podman to use iptables fixes the problem:

[network]
firewall_driver="iptables"
