REGISTER_NETDEV(9)					      Network device support						REGISTER_NETDEV(9)

NAME

       register_netdev - register a network device

SYNOPSIS

       int register_netdev(struct net_device * dev);

ARGUMENTS

       dev
	   device to register

DESCRIPTION

       Take a completed network device structure and add it to the kernel interfaces. A NETDEV_REGISTER message is sent to the netdev notifier
       chain. 0 is returned on success. A negative errno code is returned on a failure to set up the device, or if the name is a duplicate.

       This is a wrapper around register_netdevice that takes the rtnl semaphore and expands the device name if you passed a format string to
       alloc_netdev.

NAME

       device_create - creates a device and registers it with sysfs

SYNOPSIS

       struct device * device_create(struct class * class, struct device * parent, dev_t devt, void * drvdata, const char * fmt, ...);

ARGUMENTS

       class
	   pointer to the struct class that this device should be registered to

       parent
	   pointer to the parent struct device of this new device, if any

       devt
	   the dev_t for the char device to be added

       drvdata
	   the data to be added to the device for callbacks

       fmt
	   string for the device's name

       ...
	   variable arguments

DESCRIPTION

       This function can be used by char device classes. A struct device will be created in sysfs, registered to the specified class.

       A "dev" file will be created, showing the dev_t for the device, if the dev_t is not 0,0. If a pointer to a parent struct device is passed
       in, the newly created struct device will be a child of that device in sysfs. The pointer to the struct device will be returned from the
       call. Any further sysfs files that might be required can be created using this pointer.

       Returns struct device pointer on success, or ERR_PTR on error.

NOTE

       the struct class passed to this function must have previously been created with a call to class_create.
