NAME

       __dev_get_by_index - find a device by its ifindex

SYNOPSIS

       struct net_device * __dev_get_by_index  (int ifindex);

ARGUMENTS

       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.
