func CheckSCTPModuleLoadedOnNodes(ctx context.Context, f *framework.Framework, nodes *v1.NodeList) bool
CheckSCTPModuleLoadedOnNodes checks whether any node on the list has the sctp.ko module loaded For security reasons, and also to allow clusters to use userspace SCTP implementations, we require that just creating an SCTP Pod/Service/NetworkPolicy must not do anything that would cause the sctp kernel module to be loaded.
