Subject: [dpdk-dev] [PATCH 1/4] rte_mbuf: add rte_pktmbuf_coalesce
Date: Fri, 2 Dec 2016 18:07:43 +0100 [thread overview]
Message-ID: <1480698466-17620-2-git-send-email-tomaszx.kulasek@intel.com> (raw)
In-Reply-To: <1480698466-17620-1-git-send-email-tomaszx.kulasek@intel.com>
This patch adds function rte_pktmbuf_coalesce to let crypto PMD coalesce
chained mbuf before crypto operation and extend their capabilities to
support segmented mbufs when device cannot handle them natively.
