dpdk的版本是1.7.1的稳定版，服务器是ubuntu12.04LTS x86 64bit

绑定万兆网卡的默认驱动ixgbe失败

# ./dpdk_nic_bind.py -b ixgbe 06:00.1
Error: bind failed for 0000:06:00.1 - Cannot bind to driver ixgbe

查看原因 dmesg |tail

# dmesg |tail
[ 5667.433649] ixgbe 0000:06:00.1: failed to load because an unsupported SFP+ module type was detected.
[ 5667.433953] ixgbe 0000:06:00.1: Reload the driver after installing a supported module.
[ 5667.434282] ixgbe 0000:06:00.1: PCI INT B disabled

发现原因是光模块不支持

解决办法是换两块intel的光模块
