Subject: [dpdk-dev] [PATCH v3 4/6] net/mlx5: update Rx datapath to support split
Date: Mon, 26 Oct 2020 10:11:57 +0000 [thread overview]
Message-ID: <1603707119-20672-5-git-send-email-viacheslavo@nvidia.com> (raw)
In-Reply-To: <1603707119-20672-1-git-send-email-viacheslavo@nvidia.com>
Only the regular rx_burst routine is updated to support split,
because the vectorized ones does not support scatter and MPRQ
does not support split at all.
