            Bug ID: 1573
           Summary: NIC latency issue on the AsyncSniffer callback
                    function
           Product: DPDK
           Version: unspecified
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: DTS
          Assignee: dev@dpdk.org

  Target Milestone: ---

There exists a bug on i40e NICs where the AsyncSniffer does not capture sent
packets forwarded by the callback function. As if now, it's unclear why this
would be the case, but there is a temporary fix that adds a simple one second
delay to the callback function and packet sniffing duration before sending out
any packets. This temporary fix allows test cases to perform as expected on
i40e devices while maintaining the output of other vendors as well. It is in
the best interest of the framework to find a better solution to this problem,
but for the time being, this temporary fix will suffice.

This ticket will remain open until such a time arises where a better solution
is proposed once further research is conducted.
