Subject: [dpdk-dev] [PATCH v4 1/4] ethdev: introduce generic IP/UDP tunnel checksum and TSO
Date: Sun, 8 Apr 2018 20:32:37 +0800 [thread overview]
Message-ID: <20180408123240.110698-2-xuemingl@mellanox.com> (raw)
In-Reply-To: <20180408123240.110698-1-xuemingl@mellanox.com>
In-Reply-To: <20180109141110.146250-2-xuemingl@mellanox.com>
This patch introduce new TX offload flags for device that supports
IP or UDP tunneled packet L3/L4 checksum and TSO offload.
The support from the device is for inner and outer checksums on
IPV4/TCP/UDP and TSO for *any packet with the following format*:
<some headers> / [optional IPv4/IPv6] / [optional TCP/UDP] / <some
headers> / [optional inner IPv4/IPv6] / [optional TCP/UDP]
For example the following packets can use this feature:
1. eth / ipv4 / udp / VXLAN / ip / tcp
2. eth / ipv4 / GRE / MPLS / ipv4 / udp
Please note that tunnel headers that contain payload length, sequence id
or checksum will not be updated.
