Since distro kernels appear to set CONFIG_NET_NS, doesn't this
effectively disable debugfs for bonding on most distros?
Do the other network device drivers that support debugfs have a
similar problem? E.g., if each of two namespaces have an skge device
with the same name, will there be a debugfs conflict there as well?
