Hi Paul, Looks like your ConnectX-3 configured to be IB and not ETH
> pci@0000:04:00.0 ib0 network MT27500 Family [ConnectX-3] Use connectx_port_config script. Set all the ports to Ethernet, and follow the instructions on the screen. You can use -w to specify ConnectX-3 PCI address, you don't need to use -b Make sure you compile DPDK with mlx4 PMD, it is not enabled by default Best Regards, Olga > -----Original Message----- > From: users [mailto:[email protected]] On Behalf Of Paul Tsvika > Sent: Monday, July 31, 2017 1:14 PM > To: [email protected] > Subject: [dpdk-users] [dpdk][pktgen] - execute pktgen with mlx4 (40G) with > some errors > > Hi, > > Below is my configuration: > > AOC: Mellanox MT27500 Family [ConnectX-3] > OS: Ubuntu 16.04 > DPDK version: 17.05.1 > Pktgen: 3.3.8 > Memory: 16G > CPU: Intel(R) Xeon(R) CPU D-1557 (12C) > > I've enabled the configuration in dpdk (CONFIG_RTE_LIBRTE_MLX4_PMD=y) > and installed Mellanox OFED > <https://emea01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fw > ww.mellanox.com%2Fpage%2Fproducts_dyn%3Fproduct_family%3D26%26 > mtag%3Dlinux_sw_drivers&data=02%7C01%7Colgas%40mellanox.com%7C4f > e2f94155994a2a579008d4d7fce66a%7Ca652971c7d2e4d9ba6a4d149256f461b > %7C0%7C0%7C636370928586578406&sdata=%2FPnEAOJFsGtQRY%2FP5u0Hpl > L6kDbnhwRGIgSV%2B31w40Q%3D&reserved=0> > driver and recompiled DPDK.
