Subject: [dpdk-dev] [PATCH v3 07/12] mbuf: new flag for LRO
Date: Thu, 13 Oct 2016 16:16:06 +0200 [thread overview]
Message-ID: <1476368171-18176-8-git-send-email-olivier.matz@6wind.com> (raw)
In-Reply-To: <1476368171-18176-1-git-send-email-olivier.matz@6wind.com>
When receiving coalesced packets in virtio, the original size of the
segments is provided. This is a useful information because it allows to
resegment with the same size.
Add a RX new flag in mbuf, that can be set when packets are coalesced by
a hardware or virtual driver when the m->tso_segsz field is valid and is
set to the segment size of original packets.
This flag is used in next commits in the virtio pmd.
