            Bug ID: 540
           Summary: ixgbe: Intel 82599 4*10 NIC with 1000BASE-T SFP
                    transceiver does not work for the first port.
           Product: DPDK
           Version: 20.08
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: Normal
         Component: ethdev
          Assignee: dev@dpdk.org
          Reporter: mahx@arraynetworks.com.cn
  Target Milestone: ---

Hardware and System info:
   NIC: Intel 82599 4*10G NIC
   SFP modle: 1000BASE-T SFP transceiver (Finisar FCLF8521P2BTL)
   System: CentOS 7.2
   DPDK version: 20.08

Operation:=20
1. plug in the 1000BASE-T SFP module
2. Start testpmd
3. Connect the cable to a switch or another NIC

Result:
1. For the first port (the top port) of the NIC:=20
    The Link state is always DOWN and the LED on the NIC is always off.=20
    But the link is up and the LED in on for the peer NIC(or switch).
2. For the other 3 port of the NIC:=20
    The behaviour is normal.

I test on two Intel 82599 4*10G NICs, the test result are the same.
And I test with Linux Kernel driver with the same case, the behaviour is no=
mal
for all 4 ports.
So it is not a harware issue.
