net/sched: act_police: Add extack messages for offload failure
For better error reporting to user space, add extack messages when
police 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 police rate 100Mbit burst 10000
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. 21.592969: netlink_extack: msg=act_police: Offload not supported when conform/exceed action is "reclassify"
tc-182 [000] ..... 21.592982: netlink_extack: msg=cls_matchall: Failed to setup flow action
# tc filter add dev dummy0 ingress pref 1 proto all matchall skip_sw action police rate 100Mbit burst 10000 conform-exceed drop/continue
Error: cls_matchall: Failed to setup flow action.
We have an error talking to the kernel
# cat /sys/kernel/tracing/trace_pipe
tc-184 [000] b..1. 38.882579: netlink_extack: msg=act_police: Offload not supported when conform/exceed action is "continue"
tc-184 [000] ..... 38.882593: netlink_extack: msg=cls_matchall: Failed to setup flow action
