net/sched: act_mpls: Add extack messages for offload failure
For better error reporting to user space, add extack messages when mpls
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 mpls dec_ttl
Error: cls_matchall: Failed to setup flow action.
We have an error talking to the kernel
# cat /sys/kernel/tracing/trace_pipe
tc-182 [000] b..1. 18.693915: netlink_extack: msg=act_mpls: Offload not supported when "dec_ttl" option is used
tc-182 [000] ..... 18.693921: netlink_extack: msg=cls_matchall: Failed to setup flow action
