Hi Dmitry, I'm glad I could help! By the way, you can also avoid using the PMD igb driver entirely if you don't need it (I don't as I just care about 10Gbit interfaces, but since you have lots of 82576 NICs I'm not that sure); just change your compile configuration, either the default one or a custom one (depending on what you are using): pino:~/dpdk-1.2.3r4 -> grep IGB config/defconfig_x86_64-marco-linuxapp-gcc # Compile burst-oriented IGB PMD driver CONFIG_RTE_LIBRTE_IGB_PMD=n CONFIG_RTE_LIBRTE_IGB_DEBUG_INIT=n CONFIG_RTE_LIBRTE_IGB_DEBUG_RX=n CONFIG_RTE_LIBRTE_IGB_DEBUG_TX=n CONFIG_RTE_LIBRTE_IGB_DEBUG_TX_FREE=n CONFIG_RTE_LIBRTE_IGB_DEBUG_DRIVER=n As you can see here I keep using the kernel space igb driver: pino:~/dpdk-1.2.3r4 -> lspci -kD | grep -A 2 -i ether 0000:02:00.0 Ethernet controller: Mellanox Technologies MT26448 [ConnectX EN 10GigE, PCIe 2.0 5GT/s] (rev b0) Subsystem: Mellanox Technologies Device 0016 Kernel driver in use: mlx4_core 0000:03:00.0 Ethernet controller: Intel Corporation 82599EB 10-Gigabit SFI/SFP+ Network Connection (rev 01) Subsystem: Intel Corporation Ethernet Server Adapter X520-2 Kernel driver in use: igb_uio 0000:03:00.1 Ethernet controller: Intel Corporation 82599EB 10-Gigabit SFI/SFP+ Network Connection (rev 01) Subsystem: Intel Corporation Ethernet Server Adapter X520-2 Kernel driver in use: igb_uio 0000:04:00.0 Ethernet controller: Intel Corporation 82599EB 10-Gigabit SFI/SFP+ Network Connection (rev 01) Subsystem: Intel Corporation Ethernet Server Adapter X520-2 Kernel driver in use: igb_uio 0000:04:00.1 Ethernet controller: Intel Corporation 82599EB 10-Gigabit SFI/SFP+ Network Connection (rev 01) Subsystem: Intel Corporation Ethernet Server Adapter X520-2 Kernel driver in use: igb_uio 0000:05:00.0 Ethernet controller: Intel Corporation 82576 Gigabit Network Connection (rev 01) Subsystem: Super Micro Computer Inc Device 10c9 Kernel driver in use: igb 0000:05:00.1 Ethernet controller: Intel Corporation 82576 Gigabit Network Connection (rev 01) Subsystem: Super Micro Computer Inc Device 10c9 Kernel driver in use: igb Regards, Marco
