cilium startup issue with minikube

On using kubectl apply -f cilium-spire.yaml, I got following:

level=error msg="Command execution failed" cmd="[ip6tables -w 5 -t raw -N CILIUM_OUTPUT_raw]" error="exit status 3" subsys=iptables
level=warning msg="ip6tables v1.8.4 (legacy): can't initialize ip6tables table `raw': Table does not exist (do you need to insmod?)" subsys=iptables
level=warning msg="Perhaps ip6tables or your kernel needs to be upgraded." subsys=iptables
level=error msg="Error while initializing daemon" error="cannot add custom chain CILIUM_OUTPUT_raw: exit status 3" subsys=daemon
level=fatal msg="Error while creating daemon" error="cannot add custom chain CILIUM_OUTPUT_raw: exit status 3" subsys=daemon

Modprobing ip6table_filter in minikube node didn't fix the issue (found this fix mentioned on google search).

Finally, I disabled ipv6 altogether in cilium-spire.yaml and it worked.

Any thoughts?
