+Generic Segmentation Offload Library
+====================================
+
+Overview
+--------
+Generic Segmentation Offload (GSO) is a widely used software implementation of
+TCP Segmentation Offload (TSO), which reduces per-packet processing overhead.
+Much like TSO, GSO gains performance by enabling upper layer applications to
+process a smaller number of large packets (e.g. MTU size of 64KB), instead of
+processing higher numbers of small packets (e.g. MTU size of 1500B), thus
+reducing per-packet overhead.
+
+For example, GSO allows guest kernel stacks to transmit over-sized TCP segments
+that far exceed the kernel interface's MTU; this eliminates the need to segment
+packets within the guest, and improves the data-to-overhead ratio of both the
+guest-host link, and PCI bus. The expectation of the guest network stack in this
+scenario is that segmentation of egress frames will take place either in the NIC
+HW, or where that hardware capability is unavailable, either in the host
+application, or network stack.
+
+Bearing that in mind, the GSO library enables DPDK applications to segment
+packets in software. Note however, that GSO is implemented as a standalone
+library, and not via a 'fallback' mechanism (i.e. for when TSO is unsupported
+in the underlying hardware); that is, applications must explicitly invoke the
+GSO library to segment packets. The size of GSO segments ``(segsz)`` is
+configurable by the application.
+
+Limitations
+-----------
+
+#. The GSO library doesn't check if input packets have correct checksums.
+
+#. In addition, the GSO library doesn't re-calculate checksums for segmented
+ packets (that task is left to the application).
+
+#. IP fragments are unsupported by the GSO library.
+
+#. The egress interface's driver must support multi-segment packets.
+
+#. Currently, the GSO library supports the following IPv4 packet types:
+
+ - TCP
+ - VxLAN
+ - GRE
+
+ See `Supported GSO Packet Types`_ for further details.
+
+Packet Segmentation
+-------------------
+
+The ``rte_gso_segment()`` function is the GSO library's primary
+segmentation API.
+
+Before performing segmentation, an application must create a GSO context object
+``(struct rte_gso_ctx)``, which provides the library with some of the
+information required to understand how the packet should be segmented. Refer to
+`How to Segment a Packet`_ for additional details on same. Once the GSO context
+has been created, and populated, the application can then use the
+``rte_gso_segment()`` function to segment packets.
+
+The GSO library typically stores each segment that it creates in two parts: the
+first part contains a copy of the original packet's headers, while the second
+part contains a pointer to an offset within the original packet. This mechanism
+is explained in more detail in `GSO Output Segment Format`_.
+
+The GSO library supports both single- and multi-segment input mbufs.
+
+GSO Output Segment Format
+~~~~~~~~~~~~~~~~~~~~~~~~~
+To reduce the number of expensive memcpy operations required when segmenting a
+packet, the GSO library typically stores each segment that it creates as a
+two-part mbuf (technically, this is termed a 'two-segment' mbuf; however, since
+the elements produced by the API are also called 'segments', for clarity the
+term 'part' is used here instead).
+
+The first part of each output segment is a direct mbuf and contains a copy of
+the original packet's headers, which must be prepended to each output segment.
+These headers are copied from the original packet into each output segment.
+
+The second part of each output segment, represents a section of data from the
+original packet, i.e. a data segment. Rather than copy the data directly from
+the original packet into the output segment (which would impact performance
+considerably), the second part of each output segment is an indirect mbuf,
+which contains no actual data, but simply points to an offset within the
+original packet.
+
+The combination of the 'header' segment and the 'data' segment constitutes a
+single logical output GSO segment of the original packet. This is illustrated
+in :numref:`figure_gso-output-segment-format`.
+
+.. _figure_gso-output-segment-format:
+
+.. figure:: img/gso-output-segment-format.svg
+ :align: center
+
+ Two-part GSO output segment
+
+In one situation, the output segment may contain additional 'data' segments.
+This only occurs when:
+
+- the input packet on which GSO is to be performed is represented by a
+ multi-segment mbuf.
+
+- the output segment is required to contain data that spans the boundaries
+ between segments of the input multi-segment mbuf.
+
+The GSO library traverses each segment of the input packet, and produces
+numerous output segments; for optimal performance, the number of output
+segments is kept to a minimum. Consequently, the GSO library maximizes the
+amount of data contained within each output segment; i.e. each output segment
+``segsz`` bytes of data. The only exception to this is in the case of the very
+final output segment; if ``pkt_len`` % ``segsz``, then the final segment is
+smaller than the rest.
+
+In order for an output segment to meet its MSS, it may need to include data from
+multiple input segments. Due to the nature of indirect mbufs (each indirect mbuf
+can point to only one direct mbuf), the solution here is to add another indirect
+mbuf to the output segment; this additional segment then points to the next
+input segment. If necessary, this chaining process is repeated, until the sum of
+all of the data 'contained' in the output segment reaches ``segsz``. This
+ensures that the amount of data contained within each output segment is uniform,
+with the possible exception of the last segment, as previously described.
+
+:numref:`figure_gso-three-seg-mbuf` illustrates an example of a three-part
+output segment. In this example, the output segment needs to include data from
+the end of one input segment, and the beginning of another. To achieve this,
+an additional indirect mbuf is chained to the second part of the output segment,
+and is attached to the next input segment (i.e. it points to the data in the
+next input segment).
+
+.. _figure_gso-three-seg-mbuf:
+
+.. figure:: img/gso-three-seg-mbuf.svg

+
+Supported GSO Packet Types
+--------------------------
+
+TCP/IPv4 GSO
+~~~~~~~~~~~~
+TCP/IPv4 GSO supports segmentation of suitably large TCP/IPv4 packets, which
+may also contain an optional VLAN tag.
+
+VxLAN GSO
+~~~~~~~~~
+VxLAN packets GSO supports segmentation of suitably large VxLAN packets,
+which contain an outer IPv4 header, inner TCP/IPv4 headers, and optional
+inner and/or outer VLAN tag(s).
+
+GRE GSO
+~~~~~~~
+GRE GSO supports segmentation of suitably large GRE packets, which contain
+an outer IPv4 header, inner TCP/IPv4 headers, and an optional VLAN tag.
+
+How to Segment a Packet
+-----------------------
+
+To segment an outgoing packet, an application must:
+
+#. First create a GSO context ``(struct rte_gso_ctx)``; this contains:
+
+ - a pointer to the mbuf pool for allocating the direct buffers, which are
+ used to store the GSO segments' packet headers.
+
+ - a pointer to the mbuf pool for allocating indirect buffers, which are
+ used to locate GSO segments' packet payloads.
+
+.. note::
+
+ An application may use the same pool for both direct and indirect
+ buffers. However, since each indirect mbuf simply stores a pointer, the
+ application may reduce its memory consumption by creating a separate memory
+ pool, containing smaller elements, for the indirect pool.
+
+ - the size of each output segment, including packet headers and payload,
+ measured in bytes.
+
+ - the bit mask of required GSO types. The GSO library uses the same macros as
+ those that describe a physical device's TX offloading capabilities (i.e.
+ ``DEV_TX_OFFLOAD_*_TSO``) for gso_types. For example, if an application
+ wants to segment TCP/IPv4 packets, it should set gso_types to
+ ``DEV_TX_OFFLOAD_TCP_TSO``. The only other supported values currently
+ supported for gso_types are ``DEV_TX_OFFLOAD_VXLAN_TNL_TSO``, and
+ ``DEV_TX_OFFLOAD_GRE_TNL_TSO``; a combination of these macros is also
+ allowed.
+
+ - a flag, that indicates whether the IPv4 headers of output segments should
+ contain fixed or incremental ID values.
+
+2. Set the appropriate ol_flags in the mbuf.
+
+ - The GSO library use the value of an mbuf's ``ol_flags`` attribute to
+ to determine how a packet should be segmented. It is the application's
+ responsibility to ensure that these flags are set.
+
+ - For example, in order to segment TCP/IPv4 packets, the application should
+ add the ``PKT_TX_IPV4`` and ``PKT_TX_TCP_SEG`` flags to the mbuf's
+ ol_flags.
+
+ - If checksum calculation in hardware is required, the application should
+ also add the ``PKT_TX_TCP_CKSUM`` and ``PKT_TX_IP_CKSUM`` flags.
+
+#. Check if the packet should be processed. Packets with one of the
+ following properties are not processed and are returned immediately:
+
+ - Packet length is less than ``segsz`` (i.e. GSO is not required).
+
+ - Packet type is not supported by GSO library (see
+ `Supported GSO Packet Types`_).
+
+ - Application has not enabled GSO support for the packet type.
+
+ - Packet's ol_flags have been incorrectly set.
+
+#. Allocate space in which to store the output GSO segments. If the amount of
+ space allocated by the application is insufficient, segmentation will fail.
+
+#. Invoke the GSO segmentation API, ``rte_gso_segment()``.
+
+#. If required, update the L3 and L4 checksums of the newly-created segments.
+ For tunneled packets, the outer IPv4 headers' checksums should also be
+ updated. Alternatively, the application may offload checksum calculation
+ to HW.
