From fd23e0e250c6a7a7fd8a2ec9ab4253299471c163 Mon Sep 17 00:00:00 2001 From: Ido Schimmel Date: Thu, 7 Apr 2022 10:35:33 +0300 Subject: [PATCH] net/sched: flower: Avoid overwriting error messages The various error paths of tc_setup_offload_action() now report specific error messages. Remove the generic messages to avoid overwriting the more specific ones. Before: # tc filter add dev dummy0 ingress pref 1 proto ip flower skip_sw dst_ip 198.51.100.1 action police rate 100Mbit burst 10000 Error: cls_flower: Failed to setup flow action. We have an error talking to the kernel After: # tc filter add dev dummy0 ingress pref 1 proto ip flower skip_sw dst_ip 198.51.100.1 action police rate 100Mbit burst 10000 Error: act_police: Offload not supported when conform/exceed action is "reclassify".
