To configure various complex flows we for sure can create custom pktgen init scripts, but sometimes thats not that easy. New "-a" (append) option in all the existing sample scripts allows to append more "devices" into pktgen threads. The most straightforward usecases for that are: - using multiple devices. We have to generate full linerate on all physical functions (ports) of our multiport device. - pushing multiple flows (with different packet options) Signed-off-by: Igor Russkikh <irusskikh@marvell.com> --- samples/pktgen/README.rst | 17 +++++++++++ samples/pktgen/functions.sh | 7 ++++- samples/pktgen/parameters.sh | 7 ++++- samples/pktgen/pktgen_sample01_simple.sh | 22 ++++++++------ samples/pktgen/pktgen_sample02_multiqueue.sh | 28 +++++++++-------- .../pktgen_sample03_burst_single_flow.sh | 12 +++++--- samples/pktgen/pktgen_sample04_many_flows.sh | 14 +++++---- .../pktgen/pktgen_sample05_flow_per_thread.sh | 14 +++++---- ...sample06_numa_awared_queue_irq_affinity.sh | 30 +++++++++++-------- 9 files changed, 101 insertions(+), 50 deletions(-)
