      This epic is for tracking and supporting the upstream redesign of DPDK core-to-lcore mapping for large AMD systems where core IDs exceed `RTE_MAX_LCORE`. 

      On AMD systems with more than 128 cores, starting DPDK without an explicit --lcores or -c option causes startup failure. This is because DPDK historically maps CPU cores 1:1 to lcores, which breaks when the core IDs exceed `RTE_MAX_LCORE`. A redesign is proposed upstream by Intel to remap core IDs to a contiguous lcore list. 

      As we are participating in reviews and tracking the evolution of the mid, this epic will collects them and eventual downstream preparation.
