Introduces packet throughput analysis for DPDK applications using the ethdev library. The analysis calculates packet throughput in both bits per second (bps) and packets per second (pps) for transmitted and received Ethernet traffic on a per-queue basis. Note that the calculation of throughput in bps requires the existence of custom profiling events in the trace Signed-off-by: Adel Belkhiri <[email protected]>
PMD threads continuously poll NIC queues, leading to constant 100% CPU usage. This analysis provides a rough estimation of how busy PMD threads are with actual work, by comparing the times they successfully retrieve packets from the NIC queue versus the times they are merely spinning without processing any packets.

Introduce packet distribution analysis for PMD threads based on ethdev library. This analysis computes the distribution of packets retrieved in a single rte_eth_rx_burst() call, on a per-queue basis. Signed-off-by: Adel Belkhiri <[email protected]>
Introduce packet distribution statistics analysis for PMD threads in the ethdev library. This analysis calculates various statistics related to the distribution of packets retrieved in a single rte_eth_rx_burst() call, on a per-thread and per-queue basis. The computed statistics include the minimum, maximum, average number of packets retrieved, as well as the standard deviation. Signed-off-by: Adel Belkhiri <[email protected]>
