From e6896163b20cc2dc1c169fa5e007243a4f9650a4 Mon Sep 17 00:00:00 2001 From: Tonghao Zhang Date: Tue, 1 Sep 2020 20:26:14 +0800 Subject: [PATCH] net: openvswitch: remove unused keep_flows keep_flows was introduced by [1], which used as flag to delete flows or not. When rehashing or expanding the table instance, we will not flush the flows. Now don't use it anymore, remove it.
