Subject: Re: [dpdk-dev] [PATCH] net/mlx5: fix completion request for inline packets
Date: Mon, 5 Aug 2019 06:40:59 +0000 [thread overview]
Message-ID: <AM0PR0502MB401956B45324216450DD45C2D2DA0@AM0PR0502MB4019.eurprd05.prod.outlook.com> (raw)
In-Reply-To: <1564926975-31571-1-git-send-email-viacheslavo@mellanox.com>
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")
