If kernel provides the attribute, show the used HW stats types.
Example:
$ 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

v1->v2:
- fix output then hw_stats is not "any" - add \n
