net/sched: act_gact: Add extack messages for offload failure
For better error reporting to user space, add extack messages when gact 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 continue Error: cls_matchall: Failed to setup flow action. We have an error talking to the kernel # cat /sys/kernel/tracing/trace_pipe tc-181 [002] b..1. 105.493450: netlink_extack: msg=act_gact: Offload of "continue" action is not supported tc-181 [002] ..... 105.493466: netlink_extack: msg=cls_matchall: Failed to setup flow action # tc filter add dev dummy0 ingress pref 1 proto all matchall skip_sw action reclassify Error: cls_matchall: Failed to setup flow action. We have an error talking to the kernel # cat /sys/kernel/tracing/trace_pipe tc-183 [002] b..1. 124.126477: netlink_extack: msg=act_gact: Offload of "reclassify" action is not supported tc-183 [002] ..... 124.126489: netlink_extack: msg=cls_matchall: Failed to setup flow action # tc filter add dev dummy0 ingress pref 1 proto all matchall skip_sw action pipe action drop Error: cls_matchall: Failed to setup flow action.
