Re: [dpdk-users] [dpdk][pktgen] - execute pktgen with mlx4 (40G) with some errors

[Olga Shern <olgas@mellanox.com>]

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
