* 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.
* Fixed MAC addresses in P4Runtime exercise starter code
* Updated ECN exercise to use new topology.json file. Updated the
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
need to update the README and figure out what we want the tutorial
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
* Renamed path_monitor exercise to link_monitor
* Updated the README in the link_monitor exercise and removed the
bits from the starter code that we want the tutorial attendees
to implement.

* Updated README files for exercises to fix some typos and added
a note about the V1Model architecture.
* Added a note about food for thought in the link_monitor README
* Updated the firewall.p4 program to use two register arrays rather

high line rate devices which can only support a single access
to each register array.
* Minor fix to firewall exercise to get rid of compiler warning.
* Updated comment in firewall exercise.
* Minor (typo) fixes in the firewall ReadMe

This could be useful for rendering the markdown README files offline.
* Updated top level README so it can be merged into the master branch.
* Moved cmd to install grip from root-bootstrap to user-bootstrap
* Adapt script to any machine
Adapt script to any machine, independent of the user. We support for installations in VM Ubuntu
* Clear user-bootstrap.sh
* Update user-bootstrap.sh
* Adapt installation script to any machine
* 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
--p4runtime-format flags
Provide standard_metadata for mark_to_drop
* Fix path for ECN exercise
Add some hints to common issues users may run into
when following the README to run the tutorials.

P4Runtime uses a "complex" error message format to report errors for
batched Write & Read RPC requests. Some effort is required to parse the
error messages appropriately in order to print some useful debugging
information.
