* Support negative-valued action parameters
by converting them in the Python helper code into a positive value
whose bit pattern is the 2's complement representation of the negative
value.
* Add new bash function used several times in install script
Also delete some old comments. These changes help to make the script
have fewer diffs with the following script that it was derived from:
https://github.com/jafingerhut/p4-guide/blob/master/bin/install-p4dev-v6.sh
* Fix copy & paste mistake
* Support negative-valued action parameters
by converting them in the Python helper code into a positive value
whose bit pattern is the 2's complement representation of the negative
value.
* Update commit SHAs of `vagrant up dev` to latest as of 2023-Jul-01
* Update vm-ubuntu-20.04/README.md for 2023-Jul-01
* Support negative-valued action parameters
by converting them in the Python helper code into a positive value
whose bit pattern is the 2's complement representation of the negative
value.
* Update versions of protobuf and grpc installed, install p4testgen
Update protobuf from v3.6.1 to v3.18.1
Update grpc from v1.17.2 to v1.43.2
Both of those versions have been long tested in the p4-guide repo
install scripts.
Update BMv2, PI, p4c, and ptf to latest versions as of 2023-Jun-24
Enable compilation of p4testgen
* Change method to install ptf
I found that the former way that I am replacing did not seem to install
it correctly.
* Make clean.sh remove sources for protobuf and grpc
Saves disk space for the image. protobuf and grpc source code is easily
obtainable from public sources if the user wishes.
* Support negative-valued action parameters
by converting them in the Python helper code into a positive value
whose bit pattern is the 2's complement representation of the negative
value.
* Update version of mininet installed to the latest available in 2023-Jun
* Support negative-valued action parameters
by converting them in the Python helper code into a positive value
whose bit pattern is the 2's complement representation of the negative
value.
* Python ipaddr package is superseded by ipaddress
* Support negative-valued action parameters
by converting them in the Python helper code into a positive value
whose bit pattern is the 2's complement representation of the negative
value.
* Add Python ply package, to enable all p4c tests to pass
They refer to bash script names that do not exist in the
vm-ubuntu-20.04 directory, and it is not straightforward and quick to
update those instructions to use scripts in the vm-ubuntu-20.04
directory without making a fair number of changes, and probably
several hours of testing those changes, that I am not prepared to make
any time soon.
The instructions _might_ be correct for the vm directory when starting
with an Ubuntu 16.04 Linux system, but that version of Ubuntu is no
longer supported, and I do not think we should be recommending its
use.
* Put latest commits for p4lang repos as of 2022-May-01 in build scripts
* Updates to steps to build behavioral-model for 2022-May
The parts of these changes on how to build simple_switch_grpc are due
to changes made in the behavioral-model recently, perhaps in 2022-Apr.
The removing of the applying of the patch is from older changes in
behavioral-model around 2022-Jan. The patch is no longer needed.
* Correction to script changes in previous commit
* Add --with-thrift option to configure command for behavioral-model
I believe that without that, the simple_switch_grpc process is built
without support for listening on the Thrift port (default value of
port is 9090).

* No longer attempt to install the Sublime Text editor during `vagrant up`
Starting around 2021-Sep, the official published instructions for
installing Sublime Text on Ubuntu Linux no longer seem to work. If
this continues for much longer, it would be a good idea if the
`vagrant up` scripts no longer attempted to install it.
* Remove remaining mentions of Sublime in directory vm-ubuntu-20.04
Function eval() calculate already the result before sending inputs to the switch (the calculation should be done by the switch) So, it should be removed.
* First draft of Ubuntu 20.04 Vagrantfile and scripts to install 2021-Mar
version of open source P4 development tools.
* Add more tracing output of what files have been installed at each step
* Don't do behavioral-model install_deps.sh before installing PI
This is an experiment to see if the end result will be able to run
tutorials basic exercise using Python3 only on an Ubuntu 20.04 system.
Just before this commit, `vagrant up` resulted in a system that failed
to run the basic exercise, because python3 failed to import
google.grpc (if I recall correctly -- it may have been a different
google.<something> Python3 module name).
* Add missing patch file
* Fix copy and paste mistake
* Add missing patch file
* Change how protobuf Python3 module files are installed
* Correct a few desktop icon file names, and add clean.sh script
* Enhance clean.sh script, and add README for manual steps in creating a VM
* Changes to try to always use Python3, never Python2, in tutorials
* Update README steps for preparing a VM
* More additions to README on steps to create a single file VM image
* Add empty-disk-block zeroing to clean.sh script
* Also install PTF
* Update versions of P4 dev tool source code to 2021-Apr-05
This includes a change to p4lang/PI that allows P4Runtime API clients
to send the shortest byte sequences necessary to encode integer
values, which I want for a PTF test that I have recently created.
* Update README for 2021-Apr-05 version of VM image
* Resolve Python 3 compatibility issues
Most of the Python 2 to 3 code translation changes
were automated with the 2to3 tool.

As of 2020-May-09, and probably some months earlier, attempting to
install the Python 'grip' package fails on Ubuntu 16.04 systems. This
package is not essential for using the P4 open source development
tools.
* Several proposed changes to v1model standard_metadata for cheat sheet
Remove several fields that are deprecated in the v1model.p4 include file,
or will be soon:
+ drop
+ recirculate_port
+ clone_spec
+ lf_field_list
+ resubmit_flag
+ recirculate_flag
Add mention of more detailed documentation in behavioral-model
repository, for those that want to know more about how each field
behaves.
Group the fields by those that are only intended to be read in a P4
program, versues read/write, and which are only intended to be useful
in ingress, egress, or both.
* Minor updates to proposed v1model standard_metadata changes
* Updated the utils/run_exercise.py to allow exercises to customize
host configuration from the topology.json file.
Now hosts and `ping` each other in the basic exercise. Other Linux
utilities should work as well (e.g. iperf).
```

Only updated basic exercise, still need to update other exercises.
Also, updated the root-bootstrap.sh because I was running into issues
with latest version of vagrant.
* Accidentially added the solution to the basic exercise in the previous
commit. Undoing that here ...
* Updated the topology.json file and table entries for the basic_tunnel
exercise.
* Updated P4Runtime exercise with new topology and table entries.
* Fixed MAC addresses in P4Runtime exercise. It is working now.

table entries / MAC addresses as well.
* Updated the topology.json file and table entries for the MRI exercise.
* Updated source_routing exercise with new topology file and verified
correct functionality.
* Updated load_balance exercise with new topology.
* Moved basic exercise triangle topology into a separate folder
* Added new topology for the basic exercise: a single pod of a fat-tree.
* Updated Makefiles and run_exercise.py to allow exercises to configure
each switch with a different P4 program. This is mainly for the
firewall exercise.
* Updated Makefiles of project to work with new utils/Makefile
* Updated load_balance and p4runtime exercise Makefiles
* Initial commit of the firewall exercise, which is a simple stateful
firewall that uses a bloom filter. Need to update README files
* Initial commit of the path_monitor exercise. It is working but still

attendees to implement.
* Updated README file in firewall exercise. Also removed the bits
from the starter code that we want the tutorial attendees to
implement

high line rate devices which can only support a single access
to each register array.

* Updated comment in firewall exercise.
* Minor (typo) fixes in the firewall ReadMe

Adapt script to any machine, independent of the user. We support for installations in VM Ubuntu
* Clear user-bootstrap.sh

* Update user-bootstrap to use latest version (#251)
* p4c tests are failing in latest version. So, let's skip it during vagrant provisioning
* Update tutorial to use latest version of P4 tools
Modify switch.py to handle setting default_action
Use --p4runtime-files instead of deprecated --p4runtime-file and
