From c019b5166e11faaf9ed3b64316ed338eaa19de60 Mon Sep 17 00:00:00 2001 From: Or Gerlitz Date: Mon, 16 Oct 2017 12:19:48 +0300 Subject: net/sched: cls_flower: Set egress_dev mark when calling into the HW driver Commit 7091d8c '(net/sched: cls_flower: Add offload support using egress Hardware device') made sure (when fl_hw_replace_filter is called) to put the egress_dev mark on persisent structure instance. Hence, following calls into the HW driver for stats and deletion will note it and act accordingly. With commit de4784ca030f this property is lost and hence when called, the HW driver failes to operate (stats, delete) on the offloaded flow. Fix it by setting the egress_dev flag whenever the ingress device is different from the hw device since this is exactly the condition under which we're calling into the HW driver through the egress port net-device.
