* xt-physdev
* xt-nflog
* xt-limit
* nfnetlink-log
Without them, the k3s network-policy-controller reports failures in the log
related to iptables-restore.

We already have docker and some other fragments that are relevant to
k3s/k8s, but the addition of ipset as a depends for k3s highlights
that we should have a reference configuration that sets all the options
for proper opration and runtime dependencies.
When k8s or k3s are distro features, we'll apply the new fragment to
any kernel that supports fragments (and matches the supported
versions).
