__dev_get_by_name - find a device by its name
struct net_device * __dev_get_by_name (const char * name);
name name to find
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.
