I think this can\nalso be useful for 100G reference, though I haven't got device to test yet.\n\nThis script simply does:\nDetect $DEV's NUMA node belonging.\nBind each thread (processor of NUMA locality) with each $DEV queue's\nirq affinity, 1:1 mapping.\nHow many '-t' threads input determines how many queues will be\nutilized.\nIf '-f' designates first cpu id, then offset in the NUMA node's cpu\nlist.\n\nTested with Intel XL710 NIC with Cisco 3172 switch.\n\nReferrences:\nhttps://people.netfilter.org/hawk/presentations/LCA2015/net_stack_challenges_100G_LCA2015.pdf\nhttp://www.intel.cn/content/dam/www/public/us/en/documents/reference-guides/xl710-x710-performance-tuning-linux-guide.pdf\n\nChange log\nv2:\n\tRebased to https://github.com/netoptimizer/network-testing/tree/master/pktgen\n\tMove helper functions to functions.sh\n\tMore concise shell grammar usage\n\tTake '-f' parameter into consideration.
