Network devices are not accessed through device nodes and they do not have major and minor numbers. Instead, a network device is allocated a name by the kernel, based on a string and an instance number. Here is an example of the way a network driver registers an interface:
my_netdev = alloc_netdev(0, "net%d", NET_NAME_UNKNOWN, netdev_setup); ret = register_netdev(my_netdev);
This creates a network device named
net0 the first time it is called,
net1 the second, and so on. More common names are
Note that this is the name it starts off with; device managers, such as
udev, may change to something different later on.
Usually, the network interface name is only used when configuring the network using utilities such as ...
