            Bug ID: 1560
           Summary: "net_txgbe" is unable to retrieve all statistical
                    information correctly through telemetry.
           Product: DPDK
           Version: 24.07
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: ethdev
          Assignee: dev at dpdk.org
          Reporter: junwang01 at cestc.cn
  Target Milestone: ---

I tried using DPDK telemetry with the X710 network card, and it was
indeed able to retrieve all xstat statistics. However, there seems to
be an issue with retrieving xstat data from the Wangxun network card
using the txgbe driver.
This might be an issue with the specific driver.
