[NET]: Add a network namespace tag to struct net_device
Please note that network devices do not increase the count count on the network namespace. The are inside the network namespace and so the network namespace tag is in the nature of a back pointer and so getting and putting the network namespace is unnecessary. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Signed-off-by: David S. Miller <davem@davemloft.net>
