            Bug ID: 815
           Summary: Incorrect average cycles print in Service Summary
           Product: DPDK
           Version: 20.11
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: eventdev
          Assignee: dev at dpdk.org
          Reporter: heng.wang at ericsson.com
  Target Milestone: ---

The avg is incorrect in the service summary:

========[ Services ]========
Services Summary
  red_0: stats 1        calls 4116836818        cycles 1895089655988    avg: 0
  txa_0: stats 1        calls 1074980347        cycles 377139519878     avg:
350
  rte_event_eth_rx_adapter_0: stats 1   calls 871649367 cycles 2820073051742   
avg: 3235
  worker_service: stats 1       calls 3522889906        cycles 1017830212880   
avg: 0
  timer_service: stats 1        calls 3326551197        cycles 748157460934    
avg: 0

The avg in the last 2 rows are incorrect. I think it might be some race
condition between the service run updating the cycles, and the service print
accessing the cycles.
