Subject: [dpdk-dev] [PATCH v6 1/2] ethdev: introduce generic IP/UDP tunnel checksum and TSO
Date: Wed, 18 Apr 2018 21:58:52 +0800	[thread overview]
Message-ID: <20180418135852.27598-1-xuemingl@mellanox.com> (raw)
In-Reply-To: <20180408123240.110698-1-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.
It will be used for non-standard tunnels.

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 specific tunnel headers that contain payload length,
sequence id or checksum will not be updated.

The new flag PKT_TX_TUNNEL_IP is redundant with PKT_TX_OUTER_IP_CKSUM.
The old flag PKT_TX_OUTER_IP_CKSUM can be deprecated and removed in
later release.
