It seems stats are no longer displaying for actions.
This is a net-next kernel. I have tried kernel 3.16.0-rc2
and 3.17.0-rc4 with same results.

Simple test case:

----
root@moja-1:~# tc actions add  action drop index 4
root@moja-1:~# tc -s actions ls action gact

     action order 0: gact action drop
      random type none pass val 0
      index 4 ref 1 bind 0 installed 9 sec used 4 sec
-----

What I would have expected to see is:
---
     action order 0: gact action drop
      random type none pass val 0
      index 4 ref 1 bind 0 installed 9 sec used 4 sec
          Sent 108948 bytes 1297 pkts (dropped 1297, overlimits 0)

I'm looking into it which classifier? A basic u32 classifier attached
to the ingress qdisc seems to work. If your using u32 any hash tables,
or 'filter change' commands before this?

# tc actions add  action drop index 4

# tc filter add dev p3p1 parent ffff:0 protocol ip prio 100 \
	u32 match ip src 16.0.0.2 action gact index 4

#tc -s actions ls action gact

         action order 0: gact action drop
          random type none pass val 0
          index 4 ref 2 bind 1 installed 142 sec used 0 sec
         Action statistics:
         Sent 840 bytes 10 pkt (dropped 10, overlimits 0 requeues 0)
         backlog 0b 0p requeues 0

cheers,
jamal
