Open vSwitch does not bring up ports automatically. This is not a
problem for wireless ports, or for ports configured in
/etc/config/network, but other ports will be down, and require manual
interaction to be brought up. Configuring them with proto none will
cause netifd to do some actions on them, which might cause undefined
results, and will also bloat the UCI config file.
The cleanest solution is to bring all member ports up as part of the
init script.

Python six was required to build the OVS Python libs during the time when
they were supporting both Python 2 & 3.
Python 3 is a minimum requirement for OVS Python's libs since commits:
1ca0323e7cbd90524550
and Six is no longer required since commit
0c4d144a98
The end-goal here is to get rid of the Python Six host-build.
OVS is the only user.

When Open vSwitch is configured to use a controller, but is unable to
connect to it, Open vSwitch will setup flows to allow all traffic, if
the failure mode is not configured, or set to standalone.
As this might be a security hazard, it is also possible to configure
Open vSwitch in a secure failure mode. Enabling this mode causes Open
vSwitch to drop all traffic if it is unable to connect to the
controller.
Redirect stderr of the command to /dev/null as it does not support the
--if-exists option.

Due to a copy-paste error, libopenvswitch is missing a dependency when

Add a UCI config option to set the OpenFlow datapath description. This
allows setting a human readable description of the bridge, e.g.
"Building x, Floor y, AP z", which makes it easier to recognize the AP.

The Open vSwitch init script does not set USE_PROCD=1. Instead, it
defines most of the functions and variables that would be set when
USE_PROCD is set to 1, but with some minor changes.
The basescript variable however, which is used when calling
procd_open_service and procd_kill, is not set. As a result, basename of
the contents of the initscript variable is used as the service name. As
the service is automatically started via its symlink in /etc/rc.d,
S15openvswitch, the service name is S15openvswitch.
Set the basescript variable so that the service name is openvswitch.

By default, Open vSwitch will generate the OpenFlow datapath ID of a
bridge based on the MAC address of one of its ports. Due to this, it's
possible that the datapath ID changes when new ports are added. When the
datapath ID changes, Open vSwitch disconnects from the controller, as
there is no way to notify the controller that the datapath ID has
changed.
Add an option to set the datapath ID so that the above situation can be
avoided. The option takes either exactly 16 hex characters, or when
prefixed with 0x, between 1 and 16 hex characters.

Installing openvswitch on an x86/64 snapshot image pulls in a bunch of
dependencies, good for a total size of 3648406 byte. Disabling
libunbound reduces that with 559941 byte, for a total of 3088465 byte.
This is quite a big reduction for a small tradeoff: without libunbound,
hostnames can not be used to specify OpenFlow managers or controllers.

The current way to add ports to an Open vSwitch bridge does not allow
complex port configurations. Use a dedicated uci config section per port
instead of the current port:type syntax. This way we can easily support
more features like setting the VLAN tag or the OpenFlow port number.

Calling the ovs_bridge_init function when stopping the service will
result in ovs-vsctl being called after ovsdb-server has been shut down.
This causes the following error:
ovs-vsctl: unix:/var/run/openvswitch/db.sock: database connection failed (No such file or directory)
Calling the ovs_bridge_init function when requesting the service status
has no added value.
Only call ovs_bridge_init during start or restart to fix this.

This is to make explicit the conditional select of libunwind is only
needed for libopenvswitch. If we spill it over other packages, the
generated kconfig will have recursive dependency issue. 2 new patches
were made for this goal
The other thing is that "+libunwind" will cause it to be built if any of the
packages defined in this Makefile is enabled (y or m). This is at the moment
by-design of the build system.
Libunwind does not support architectures like arc. Use conditional select To
avoid (libunwind) build failures like the following,
checking for ELF helper width... configure: error: Unknown ELF target: arc
make[3]: *** [Makefile:65: /data/openwrt/build_dir/target-arc_arc700_uClibc/
libunwind-1.3.1/.configured_68b329da9893e34099c7d8ad5cb9c940] Error 1
Things like "+PACKAGE_openvswitch-libopenvswitch:libunwind" will also result in
recursive deps error for chains of 3 nodes. Kconfig construct like the
following will be made
config A
tristate
select B
depends on !(C) || (x)
config B
tristate
select C
config C
tristate
config x
bool
Other changes include
- Shared use of variable ovs__common_depends was removed
- Ovn doc build was patched out

This is a workaround to prevent the whole build from failing because of
the intree kmods are not supported yet by upstream project.
Root cause is that kernel version should not play a part when making
DEPENDS as the generated kconfig was for all targets that may have
different kernel versions.
One less than ideal effect of this change is that for an unsupported
kernel version, people can still select the intree kmod but it won't be
built. This may contradict expectation if the warning was not noticed
by them
