From 2ca9f9b837ce919a1754f4e7ef0f516e1ad1aec0 Mon Sep 17 00:00:00 2001 From: Chris Mi Date: Fri, 10 Mar 2023 09:56:08 +0200 Subject: [PATCH] net/mlx5: E-switch, Don't destroy indirect table in split rule [ Upstream commit 4c8189302567f75099a336b0efcff8291ec86ff4 ] Source port rewrite (forward to ovs internal port or statck device) isn't supported in the rule of split action. So there is no indirect table in split rule. The cited commit destroyes indirect table in split rule. The indirect table for other rules will be destroyed wrongly. It will cause traffic loss. Fix it by removing the destroy function in split rule. And also remove the destroy function in error flow.
