From ecd867faa860b41a154b3e24f6ea4536562234ab Mon Sep 17 00:00:00 2001 From: Reshma Pattan Date: Fri, 4 May 2018 11:47:06 +0100 Subject: [PATCH] test/reorder: fix freeing mbuf twice mbufs are being freed twice in error, once in rte_mempool_put_bulk() and then in rte_reorder_free(). Refactor the code so that we use rte_reorder_free() to free mbufs in the reorder buffer, and use rte_pktmbuf_free() to free any unused or drained mbufs.
