As mentioned by Alexei last week in Budapest, it is a bit weird to take a spinlock in order to drop a packet in a tc filter... Lets add percpu infra for tc actions and use it for gact & mirred. Before changes, my host with 8 RX queues was handling 5 Mpps with gact, and more than 11 Mpps after. Mirred change is not yet visible if ifb+qdisc is used, as ifb is not yet multi queue enabled, but is a step forward.
