From d98612b8c1150cb73ecd45e94c62de053f89441c Mon Sep 17 00:00:00 2001 From: Lorand Jakab Date: Mon, 6 Oct 2014 05:45:32 -0700 Subject: [PATCH] openvswitch: Remove flow member from struct ovs_skb_cb The 'flow' memeber was chosen for removal because it's only used in ovs_execute_actions() we can pass it as argument to this function.
