From d0cc0853640d81397572d8152d068cd673a3e739 Mon Sep 17 00:00:00 2001 From: Paul Blakey Date: Mon, 23 Jan 2023 10:46:10 +0200 Subject: [PATCH] net/mlx5e: TC, Remove multiple ct actions limitation Multiple ct actions was not supported when only chain was restored on misses, as CT is a modifying action which could modify the packet and cause the sw ct rule to not match again and continue processing. Now that the misses continue from the relevant tc ct action in software, this case is supported. Remove this limitation.
