[dpdk-dev] [PATCH] net/mlx5: fix completion request for inline packets

[Matan Azrad]

From: Viacheslav Ovsiienko
> If packets are completely inline the mbuf is freed immediately after data
> copying and no pointer is stored into elts array to be free on completion. This
> leads the elts_head is not updated and completion request buffer counter
> works incorrect.
> This patch decrements the base value elts_comp used to calculate counter
> threshold and completion requests flags are set more correctly on the base
> of MLX5_TX_COMP_THRESH value.
> 
> Fixes: 18a1c20044c0 ("net/mlx5: implement Tx burst template")
