A new parameter can be put in the *.test files so that the requested
traffic is not generated at once, but slowly increasing up to the
requested traffic. This is important for some SW switched that adapt and
learn from the applied traffic. When suddenly applying a high traffic,
the switch might not have enough time to learn and lose packets. Only
after a period of time (up to 10 seconds?), the switch can cope with the
traffic without packet loss. In order to get reproducible results in
this case with low packet loss, please put the parameter ramp_step in
the test section of the *.test file. The step is expressed in percentage
of a 10Gb/s traffic. If the parameter is not present, the load will be
immediately applied.
When the runrapid.py script is now finished, it also copies the prox.log
files from all the prox instances. In case of issues, please investigate
this log file.
When using background traffic, the tool will also print the average
background traffic for each step in the DEBUG log. In this way, you can
check that the background traffic is actually dealing with the same
amount of traffic as the foreground. The tool is printing the packet
reception rate of the background generators.
A bug was also fixed regarding the latency percentile reporting. When
using tests involving l2gen.cfg, the values of the percentile latency
were wrong.

UDP and IP packet length and source UDP port and destination UDP port
were wrongly set for IPv6 packets.
In the *.test files, there is now an optional boolean field (ipv6) in
the [TestParameters] section. When set to true, the generator will use
the IPv6 packet layout to place the right values at the proper offset
in the packet. If not present or set to false, the IPv4 layout will be
used. Note also that packet size needs to be at least 84 bytes for IPV6
traffic since we need space for latency and other information in each
packet.
Packet loss ratio is now printed as a percentage of the total packets
sent.

The IRQ test has been reworked to increase the accuracy of the IRQ
measurements. Results can now also be pushed to a Prometheus push
gateway or to OPNFV's Xtesting. In order to do so, a new file
format.yaml has been introduced. Please use this file now to specify the
details of the PushGateway or the Xtesting server.
Added new test: increment_till_fail.test

Using vfio in stead of igb_uio. DPDK 2020.5 is NOT compiling the igb_uio
driver by default any more.
For the l3 mode, we are now using the new PROX vdev feature. This is
achieved by adding the vdev parameter in the port section of the PROX
config files. One of the advantages is that we can now ping a port
managed by PROX: the requests will be forwarded by PROX to the LINUX
stack, who will reply to the ping. A tap device is being created by PROX
to support this feature.
Installing old version of nasm since latest causes some issues.
If not pushgateway is being used, it should be commented out in the
config_file.
vfio is now loaded by specifying the module in /etc/modules-load.d
There is also an after_boot.sh script that will be run by
check_prox_system_setup.sh, which can be used for further configuration
of the instance after boot.
There is now also a file created /opt/rapid/system_ready_for_rapid by
the check_prox_system_setup.sh script. This file is created once all
configuration is done. The runrapid.py script will wait till this file
is created before executing any tests.

New files created in 2020 have now the right date in the copyright

IPV6 test has been added. The generator will now generate IPV6 packets
using NDP to resolve MAC addresses. The hex IP addresses in the inline
definition of the packets in the cfg files is now calculated by a lua
function called in parameters.lua. The hard-coded path /home/centos has
been replaced by ~. An error in the speed calculations has been fixed.
See the RapidTest class for details. The actual number of generated
flows is now reported. If the requested number of flows is not a power
of 2, the lowest power of 2 that is larger than the requested number of
flows will be used and reported.

All packet size in the *.test files have been replaces with imix sizes.
imix is now a list of packet sizes. If you want to run with only a
pakcet size of 64, you need to specify a list containing only 1 size:
[64].
You can also specify multiple imix values by specifying a list of list
of sizes. The keyworkds in the test files are now imix & imixs.

The code has been rewritten in multiple classes and files for better
readability and maintainability. You should now also use Python3 to run
the scripts. Some of the variables in the config files have moved to
other sections. The pushgateway parameter moved to the [varia] section
of the rapid environment file.
