            Bug ID: 1138
           Summary: net/i40e all packets dropped after
                    rte_eth_dev_flow_ctrl_set
           Product: DPDK
           Version: 21.11
          Hardware: All
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: ethdev
          Assignee: dev@dpdk.org
          Reporter: hanshuang87@gmail.com
  Target Milestone: ---

My program call rte_eth_dev_flow_ctrl_set after rte_eth_dev_start. I found that
x710 dropped all packets(rx_dropped_packets in xstats).
I have used testpmd to confirm the problem:


If I stop and start the port again, packet will be received as good.
