Hello, To ensure that i understand your question, you see that ethtool shows 15 while DPDK 1024, is that correct? From my limited knowledge of the ethtool and kernel, the value of 15 is the result of some calculation between the number of msix and number of cores. Since the kernel works in interrupt mode, the number of channels that can be opened depends on the above. DPDK works in polling mode, so there is no dependency on the msix nor the cpus. We read it directly for our NIC capabilities. To summarize, these two numbers don't have to be the same and I do not see an issue. If I misunderstood, please let me know. Hello Sahithi, Have you seen my reply? |
