However, when freeing the en resources, the tx-ring QPs are released both in mlx4_en_destroy_tx_ring (one at a time) and in mlx4_en_free_resources (as a block release). Fix by eliminating the one-at-a-time release in mlx4_en_destroy_tx_ring. Signed-off-by: Jack Morgenstein Signed-off-by: Or Gerlitz Signed-off-by: David S.
