net/sched: act_skbedit: Add extack messages for offload failure
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.
We have an error talking to the kernel
# cat /sys/kernel/tracing/trace_pipe
tc-187 [002] b..1. 45.985145: netlink_extack: msg=act_skbedit: Offload not supported when "inheritdsfield" option is used
tc-187 [002] ..... 45.985160: netlink_extack: msg=cls_matchall: Failed to setup flow action
