[Spce-user] No support for kernel packet forwarding available after upgrade to 10-5-5

[Jiri Ptacnik]

thanks Richard,

- we know for sure, there was not this problem on 9.5.8 and thinking
about rollback or may be before it we try to upgrade to 11 LTS
- another observation is, it is not persistent problem, it occurs sometimes

Ownership looks good:

root at sp:~# psaxu | grep rtpengine
-bash: psaxu: command not found
root at sp:~# ps axu | grep rtpengine

                       timestamps --pidfile
