Synopsis
| struct net_device * fsfunc__dev_get_by_index ( | struct net * net, | 
|  | int ifindex ); | 
 
Arguments
- net
- 
     the applicable net namespace
     
- ifindex
- 
     index of device
     
Description
   Search for an interface by index. Returns NULL if the device
   is not found or a pointer to the device. The device has not
   had its reference counter increased so the caller must be careful
   about locking. The caller must hold either the RTNL semaphore
   or dev_base_lock.
