* net_sched: add network namespace support for tc actionsWANG Cong2016-02-251-6/+48
| | | | | | | | | | | | | | | | Currently tc actions are stored in a per-module hashtable, therefore are visible to all network namespaces. This is probably the last part of the tc subsystem which is not aware of netns now. This patch makes them per-netns, several tc action API's need to be adjusted for this. The tc action API code is ugly due to historical reasons, we need to refactor that code in the future.

* net: sched: add percpu stats to actionsEric Dumazet2015-07-081-1/+2
| | | | | | | | | | | | | Reuse existing percpu infrastructure John Fastabend added for qdisc. This patch adds a new cpustats parameter to tcf_hash_create() and all actions pass false, meaning this patch should have no effect yet.
