__DEV_GET_BY_NAME(9) Network device support __DEV_GET_BY_NAME(9)NAME
__dev_get_by_name - find a device by its name
SYNOPSIS
struct net_device * __dev_get_by_name(struct net * net, const char * name);
ARGUMENTS
net
the applicable net namespace
name
name to find
DESCRIPTION
Find an interface by name. Must be called under RTNL semaphore or dev_base_lock. If the name is found a pointer to the device is returned.
If the name is not found then NULL is returned. The reference counters are not incremented so the caller must be careful with locks.

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.
