net/sched: cls_flower: Use mask for addr_type

Paul Blakey · davem330 · commit 970bfcd09791 · 2016-12-17T10:44:35.000-05:00
When addr_type is set, mask should also be set. Fixes: 66530bd ('sched,cls_flower: set key address type when present') Fixes: bc3103f ('net/sched: cls_flower: Classify packet in ip tunnels') Signed-off-by: Paul Blakey <paulb@mellanox.com> Reviewed-by: Roi Dayan <roid@mellanox.com> Acked-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S.
