Most likely the DPDK E1000 driver doesn't support the full range of PCI device id's as the kernel driver. What is PCI information for you? I have similar device on this machine. $ lspci -n -s 00:1f.6 00:1f.6 0200: 8086:15fc (rev 20) In my case the part that matters is the 15fc. Looking in DPDK drivers/net/e1000/base/e1000_hw.h, there is no #define for that type and no entry in drivers/net/e1000/em_ethdev.c:pci_id_em_map[] In linux kernel the entry is: drivers/net/ethernet/intel/e1000e/hw.h:#define E1000_DEV_ID_PCH_TGP_I219_V13 0x15FC The Intel drivers are not in sync. It is up to the E1000 DPDK maintainers to solve. Note: this older E1000 hardware is not fast, and using DPDK except as a test bed is really not worth it. </blockquote></div>
