selftests/tc-testings cgroup.json test failed

Hi Zhengchao,

I tried run cgroup.json (and flow.json) with linux 6.3 and iproute 6.3.
But almost test failed. e.g.

All test results:

1..56
not ok 1 6273 - Add cgroup filter with cmp ematch u8/link layer and drop action
        Could not match regex pattern. Verify command output:
filter protocol ip pref 1 cgroup chain 0
filter protocol ip pref 1 cgroup chain 0 handle 0x1
        action order 1: gact action drop
         random type none pass val 0
         index 1 ref 1 bind 1


not ok 2 4721 - Add cgroup filter with cmp ematch u8/link layer with trans flag and pass action
        Could not match regex pattern. Verify command output:
filter protocol ip pref 1 cgroup chain 0
filter protocol ip pref 1 cgroup chain 0 handle 0x1
        action order 1: gact action pass
         random type none pass val 0
         index 1 ref 1 bind 1


I saw the matchPattern checks ".*cmp..." which is not exist with my tc output.

"matchPattern": "^filter protocol ip pref [0-9]+ cgroup chain [0-9]+.*handle 0x1.*cmp\\(u8 at 0 layer 0 mask 0xff gt 10\\)",

So which tc version are you using? Am I missed something?

Thanks
