The initial website page is difficult to read because of
the large amount of links from different parts of the whole
documentation. Most of all those links come from their
index page referenced in the section 'Contents' on the side.
Another issue is that because the page is static, new links
might not get included.
This patch simplifies the main page by highlighting the project
level documentation. The static part is reduced to the main
level index pages.
All the links are available by clicking on 'Full Table of
Contents' at the end of Documentation section.

There are various L3 encapsulation standards using UDP being discussed to
leverage the UDP based load balancing capability of different networks.
MPLSoUDP (__ https://tools.ietf.org/html/rfc7510) is one among them.
The Bareudp tunnel provides a generic L3 encapsulation support for
tunnelling different L3 protocols like MPLS, IP, NSH etc. inside a UDP
tunnel.
An example to create bareudp device to tunnel MPLS traffic is
given
$ ovs-vsctl add-port br_mpls udp_port -- set interface udp_port \
type=bareudp options:remote_ip=2.1.1.3
options:local_ip=2.1.1.2 \
options:payload_type=0x8847 options:dst_port=6635
The bareudp device supports special handling for MPLS & IP as
they can have multiple ethertypes. MPLS procotcol can have ethertypes
ETH_P_MPLS_UC (unicast) & ETH_P_MPLS_MC (multicast). IP protocol can have
ethertypes ETH_P_IP (v4) & ETH_P_IPV6 (v6).
The bareudp device to tunnel L3 traffic with multiple ethertypes
(MPLS & IP) can be created by passing the L3 protocol name as string in
the field payload_type. An example to create bareudp device to tunnel
MPLS unicast & multicast traffic is given below.::
$ ovs-vsctl add-port br_mpls udp_port -- set interface
udp_port \
type=bareudp options:remote_ip=2.1.1.3
options:local_ip=2.1.1.2 \
options:payload_type=mpls options:dst_port=6635

2.5 release is 4.5 years old and I'm not aware of anyone who actually
uses it today. Release process documentation says that there is no
strict time period for nominating a new LTS release and that usually
it happens once in a two years. So, proposing to nominate 2.13 as
our new LTS release since it's a first release that doesn't include
OVN inside, so we will formally not have to support it in this
repository in case there are major issues that might be hard to fix.

GTP, GPRS Tunneling Protocol, is a group of IP-based communications
protocols used to carry general packet radio service (GPRS) within
GSM, UMTS and LTE networks. GTP protocol has two parts: Signalling
(GTP-Control, GTP-C) and User data (GTP-User, GTP-U). GTP-C is used
for setting up GTP-U protocol, which is an IP-in-UDP tunneling
protocol. Usually GTP is used in connecting between base station for
radio, Serving Gateway (S-GW), and PDN Gateway (P-GW).
This patch implements GTP-U protocol for userspace datapath,
supporting only required header fields and G-PDU message type.

Some users would find it useful to know the particular OVS version that
introduced a feature to the OVS tree kernel module or to the OVS
userspace (DPDK) datapath implementation. This patch updates the FAQ
to include that information.
This information is primarily gleaned from the top-level NEWS file.
For most of these, I did not verify them by looking carefully through
the history, so some of them may be inaccurate, although a few people
made corrections in review.

This patch first defines the dpif interface for a datapath to support
adding, deleting, getting and dumping conntrack timeout policy.
The timeout policy is identified by a 4 bytes unsigned integer in
datapath, and it currently support timeout for TCP, UDP, and ICMP
protocols.
Moreover, this patch provides the implementation for Linux kernel
datapath in dpif-netlink.
In Linux kernel, the timeout policy is maintained per L3/L4 protocol,
and it is identified by 32 bytes null terminated string. On the other
hand, in vswitchd, the timeout policy is a generic one that consists of
all the supported L4 protocols. Therefore, one of the main task in
dpif-netlink is to break down the generic timeout policy into 6
sub policies (ipv4 tcp, udp, icmp, and ipv6 tcp, udp, icmp),
and push down the configuration using the netlink API in
netlink-conntrack.c.
This patch also adds missing symbols in the windows datapath so
that the build on windows can pass.

OVN is separated into its own repo. This commit removes the OVN source,
OVN tests, and OVN documentation. It also removes mentions of OVN from
most documentation. The only place where OVN has been left is in
changelogs/NEWS, since we shouldn't mess with the history of the
project.
There is an exception here. The ovsdb-cluster tests rely on ovn-nbctl
and ovn-sbctl to run. Therefore those ovn utilities, as well as their
dependencies remain in the repo with this commit.

After discussion with several people, I decided to not store
configuration state in the database to be more consistent with

which will not be in the database as well and overall simplicity.
Accordingly, fragmentation handling is enabled by default.
