Hi JackyCT.Chen:

We are tracking this issue, it is a firmware issue that has been reported to the hardware team and the fix will take some time.

There is a workaround in ICE PMD, change the "no wait" to "wait_to_complete" mode when ice_interrupt_handler() updates the link status in drivers/net/ice/ice_ethdev.c:

#ifdef ICE_LSE_SPT
                if (int_fw_ctl & PFINT_FW_CTL_INTEVENT_M) {
                                PMD_DRV_LOG(INFO, "FW_CTL: link state change event");
                                ice_handle_aq_msg(dev);
                }
#else
                if (oicr & PFINT_OICR_LINK_STAT_CHANGE_M) {
                                PMD_DRV_LOG(INFO, "OICR: link state change event");
-                            ret = ice_link_update(dev, 0);
+                           ret = ice_link_update(dev, 1);
                                if (!ret)
                                                rte_eth_dev_callback_process
                                                                (dev, RTE_ETH_EVENT_INTR_LSC, NULL);
                }
#endif

Subject: RE: DPDK testpmd with E823 link status is down

Hi Qiming & dpdk dev team:

This is JackyCT.Chen from Advantech, we have a question about E823 DPDK loopback testpmd  ,
Could you please give us some advice?

We bind the E823 and X710 devices with vfio-pci driver and execute the DPDK testpmd . (detail see attached files please)

However,  both E823  "link status : down and link speed : None" , we expected that "link status : up and link speed : 10 Gbps" .
Do you have any suggestions?
