Could I also suggest the following text for the commit message:
app/test: fix reorder test failure
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.
Rgds,
Dave.
