            Bug ID: 99
           Summary: axgbe driver does not support 1G Copper 1000BASE-T
                    SFPs (Unsupported AN_CL37)
           Product: DPDK
           Version: 18.02
          Hardware: All
                OS: All
            Status: CONFIRMED
          Severity: normal
          Priority: Normal
         Component: ethdev
          Assignee: dev@dpdk.org
          Reporter: Arsalan_Awan@mentor.com
  Target Milestone: ---

Overview:

The AXGBE driver does not support 1G Copper 1000BASE-T SFPs. When any of the
DPDK test apps (such as: l2fwd, kni etc) are run, the following errors show up:

  axgbe_an_init(): Unsupported AN_CL37
  axgbe_an_enable_interrupts(): Unsupported AN_MOD_37
  axgbe_an_init(): Unsupported AN_CL37
  axgbe_an_restart(): Unsupported AN_MODE_CL37

Looking into the AXGBE driver code, it seems like the "Clause 37
Auto-Negotiation (AN_CL37)" protocol being used by these SFPs is not
yet-supported/yet-implemented in the DPDK AXGBE Poll Mode Driver.


Steps to Reproduce:

1) Setup DPDK (hugepages, igb_uio, dpdk-devbind):

  mkdir -p /mnt/huge
  mount -t hugetlbfs nodev /mnt/huge
  echo 1024 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages
  modprobe igb_uio
  dpdk-devbind -b igb_uio 03:00.4
  dpdk-devbind -b igb_uio 03:00.5

2) Run any of the DPDK examples/tests (such as: l2fwd, kni etc) and observe the
output:

  /usr/share/dpdk/examples/l2fwd/l2fwd -- -p 1 -T 1
