+* **Add function to allow releasing internal EAL resources on exit**
+
+  During ``rte_eal_init()`` EAL allocates memory from hugepages to enable its
+  core libraries to perform their tasks. The ``rte_eal_cleanup()`` function
+  releases these resources, ensuring that no hugepage memory is leaked. It is
+  expected that all DPDK applications call ``rte_eal_cleanup()`` before
+  exiting. Not calling this function could result in leaking hugepages, leading
+  to failure during initialization of secondary processes.
