Subject: [PATCH] net/mlx5: fix redundant free of Tx buffer
[ upstream commit c80711c3fbfdae1449ad1cbc6b31067087bd9561 ]
SW completion ring of Tx (txq->elts) stores individual mbufs even if a
multi-segmented packet is sent. rte_pktmbuf_free_seg() must be used when
cleaning up the completion ring. Otherwise, chained mbufs are redundantly
freed and finally it would cause a crash.
Fixes: 1d88ba171942 ("net/mlx5: refactor Tx data path")
