Date: Wed, 31 Dec 2014 11:46:44 -0800 From: John Fastabend <john.fastabend@...il.com> To: tgraf@...g.ch, sfeldma@...il.com, jiri@...nulli.us, jhs@...atatu.com, simon.horman@...ronome.com Cc: netdev@...r.kernel.org, davem@...emloft.net, andy@...yhouse.net Subject: [net-next PATCH v1 03/11] net: flow_table: add apply action argument to tables Actions may not always be applied after exiting a table. For example some pipelines may accumulate actions and then apply them at the end of a pipeline. To model this we use a table type called APPLY. Tables who share an apply identifier have their actions applied in one step.
