For better error reporting to user space, add extack messages when skbedit action offload fails. Example: # echo 1 > /sys/kernel/tracing/events/netlink/netlink_extack/enable # tc filter add dev dummy0 ingress pref 1 proto all matchall skip_sw action skbedit queue_mapping 1234 Error: cls_matchall: Failed to setup flow action. We have an error talking to the kernel # cat /sys/kernel/tracing/trace_pipe tc-185 [002] b..1. 31.802414: netlink_extack: msg=act_skbedit: Offload not supported when "queue_mapping" option is used tc-185 [002] ..... 31.802418: netlink_extack: msg=cls_matchall: Failed to setup flow action # tc filter add dev dummy0 ingress pref 1 proto all matchall skip_sw action skbedit inheritdsfield Error: cls_matchall: Failed to setup flow action.
