[dpdk-stable] [PATCH 17/67] net/mlx5: fix disabling Tx packet inlining

[Yongseok Koh]

[ backported from upstream commit 24a8f52455ff69826da460068ba1a5db17cc1085 ]

Adding 'txq_inline=0' to PMD parameter should disable Tx packet inlining
but it doesn't work properly for Enhanced Multi-Packet Send.

Fixes: 6ce84bd88919 ("net/mlx5: add enhanced multi-packet send for ConnectX-5")
