From 2279994d07ab67ff7a1d09bfbd65588332dfb6d8 Mon Sep 17 00:00:00 2001 From: pravin shelar Date: Mon, 19 Sep 2016 13:51:00 -0700 Subject: openvswitch: avoid resetting flow key while installing new flow. since commit commit db74a3335e0f6 ("openvswitch: use percpu flow stats") flow alloc resets flow-key. So there is no need to reset the flow-key again if OVS is using newly allocated flow-key. Signed-off-by: Pravin B Shelar Signed-off-by: David S.
