We attended the DPDK Summit last week and received terrific advice and encouragement. We are developing a DPDK PMD for our Arkville product which is a DPDK-aware data mover, capable of marshaling packets between FPGA/ASIC gates with AXI interfaces on one side, and the DPDK API/ABI on the other. Arkville plus a MAC looks like a line-rate-agnostic bare-bones L2 NIC. We have testpmd and our first DPDK applications running using our early-alpha Arkville PMD. This post is to ask of the DPDK community what tests, regressions, check-lists or similar verification assets we might work through before starting the process to upstream our code? We know device-specific PMDs are rather cloistered and unlikely to interfere; but still, others must have managed to find a way to fail with even an L2 baseline NIC. We don=E2=80= =99t want to needlessly repeat those mistakes. Any DPDK-specific collateral that we can use to verify and validate our codes before attempting to upstream them would be greatly appreciated. To the DPDK PMD developers, what can you share so that we are more aligned with your regressions? To the DPDK application developers, what=E2=80=99s your top gripe we might try to avoid= in our Arkville L2 baseline PMD? Thanks in advance. We won=E2=80=99t have anyone at the Dublin DPDK Summit, = but we will be at FPL2016 in two weeks. Any constructive feedback is greatly appreciated! Shepard Siegel, CTO atomicrules.com
