Sofar far pktgen have had a restriction to only use one device per kernel thread. With the new multiqueue architecture this is no longer adequate. The patch below is an effort to remove this by in pktgen configuration adding a tag to the device name a la eth0@0 etc. The tag is used for usual device config just as before. Also a new flag is introduced to mirror queue_map with sending threads smp_processor_id() QUEUE_MAP_CPU. An example: We use 4 CPU's to send to one 10g interface (eth0) and we use the new tagging to send a mix of packet sizes, 64, 576 and 1500 bytes. Also we use TX queues according to smp_processor_id() PGDEV=/proc/net/pktgen/kpktgend_0 pgset "add_device eth0@0" PGDEV=/proc/net/pktgen/kpktgend_1 pgset "add_device eth0@1" PGDEV=/proc/net/pktgen/kpktgend_2 pgset "add_device eth0@2" PGDEV=/proc/net/pktgen/kpktgend_3 pgset "add_device eth0@3" ....
