net: sched: extract common action counters update code into function
Currently, all implementations of tc_action_ops->stats_update() callback have almost exactly the same implementation of counters update code (besides gact which also updates drop counter). In order to simplify support for using both percpu-allocated and regular action counters depending on run-time flag in following patches, extract action counters update code into standalone function in act API. This commit doesn't change functionality. Signed-off-by: Vlad Buslov <vladbu@mellanox.com> Acked-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
