Dpdk::InitDpdk calls rte_eal_init with rte_args, which are command-line options without the program name (basename). A typical rte_args might look like --log-level=eal,8 --proc-type=auto or -c 0x0 -n 6.
However, rte_eal_init expects the traditional argc, argv format, including the program name. In its implementation, rte_eal_init ignores argv[0] and processes arguments starting from argv[1].
As a result, the first parameter in rte_args is ignored by DPDK.
I tested a simple fix by adding a dummy first argument, but this feels like a hack. I can submit a PR with this fix if you'd like. Let me know.
