Subject: [dpdk-dev] [PATCH 03/14] mlx4: fix TX for scattered mbufs with too many segments
Date: Mon, 23 Nov 2015 15:44:38 +0100 [thread overview]
Message-ID: <1448289889-9590-4-git-send-email-adrien.mazarguil@6wind.com> (raw)
In-Reply-To: <1448289889-9590-1-git-send-email-adrien.mazarguil@6wind.com>
Buffers with too many segments are linearized to overcome
MLX4_PMD_SGE_WR_N, unfortunately the last segment is never sent.
