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 Actual Results: (Using 1G Copper 1000BASE-T SFP) EAL: Multi-process socket /var/run/.rte_unix EAL: Probing VFIO support...

I have sent a mail to the maintainer fo the driver to take a look at this.
