Ingress queueing uses a seperate lock for serializing enqueue operations, but fails to properly protect itself against concurrent changes to the qdisc tree. Use queue_lock for now since the real fix it quite intrusive. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
