# Use MAC based names for network interfaces which are directly or indirectly # on USB and have an universally administered (stable) MAC address (second bit # is 0). Don't do this when ifnames is disabled via kernel command line or # customizing/disabling 99-default.link (or previously 80-net-setup-link.rules).

This sets a value that will # cause udevd to skip its repeated attempts at renaming the interface if the # first rename attempt fails.
