net: sched: expose HW stats types per action used by drivers

It may be up to the driver (in case ANY HW stats is passed) to select which type of HW stats he is going to use. Add an infrastructure to expose this information to user. $ tc filter add dev enp3s0np1 ingress proto ip handle 1 pref 1 flower dst_ip 192.168.1.1 action drop $ tc -s filter show dev enp3s0np1 ingress filter protocol ip pref 1 flower chain 0 filter protocol ip pref 1 flower chain 0 handle 0x1 eth_type ipv4 dst_ip 192.168.1.1 in_hw in_hw_count 2 action order 1: gact action drop random type none pass val 0 index 1 ref 1 bind 1 installed 10 sec used 10 sec Action statistics: Sent 0 bytes 0 pkt (dropped 0, overlimits 0 requeues 0) backlog 0b 0p requeues 0 used_hw_stats immediate <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
