ipv4: introduce __ip_dev_find()
ip_dev_find(net, addr) finds a device given an IPv4 source address and takes a reference on it. Introduce __ip_dev_find(), taking a third argument, to optionally take the device reference. Callers not asking the reference to be taken should be in an rcu_read_lock() protected section. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.
