ARGUMENTS

12       net

DESCRIPTION

19       Search for an interface by index. Returns NULL if the device is not
20       found or a pointer to the device. The device has not had its reference
21       counter increased so the caller must be careful about locking. The
22       caller must hold either the RTNL semaphore or dev_base_lock.
