| A few virtual drivers (bonding, dummy) predate netlink (~2003), which means that |
| the kernel had no way to dynamically create network interfaces. |
| The solution was kernel module paramter which statically precreated a list of |
| these virtual interfaces. The number was generally set to 1 by default, meaning |
| that loading the module creates one of its interface. |
| |
| For compatibility with legacy userspaces this is still kept around. We could |
| set the parameters to zero, but doing that everywhere is a pain. This just |
| patches the default values to zero. |
