31c2611b66 selftests: Introduce a new test case to tc testsuite
In this patchset, we fixed a tc bug. This patch adds the test case
that reproduces the bug. To run this test case, user should specify
an existing NIC device:
  # sudo ./tdc.py -d enp4s0f0

This test case belongs to category "flower". If user doesn't specify
a NIC device, the test cases belong to "flower" will not be run.

In this test case, we create 1M filters and all filters share the same
action. When destroying all filters, kernel should not panic. It takes
about 18s to run it.

7f6661a78a tc-testing: fix the -l argument bug in tdc.py
This patch fixes a bug in the tdc script, where executing tdc
with the -l argument would cause the tests to start running
as opposed to listing all the known test cases.

0923edf456 tc-testing: Split test case files into smaller chunks
The original submission had the test cases stored in one
monolithic file. This can be unwieldy to edit, especially as more
test cases are added. This patch removes the original tests.json
file in favour of individual ones broken down by category.

1d51f65a36 tc-testing: add test for testing ife type
This patch adds a new testcase for the IFE type setting in tc. In case
of user specified the type it will check if the ife is correctly
configured to react on it. If it's not specified the default IFE type
should be used.

76b903ee19 selftests: Introduce tc testsuite
Add the beginnings of a testsuite for tc functionality in the kernel.
These are a series of unit tests that use the tc executable and verify
the success of those commands by checking both the exit codes and the
output from tc's 'show' operation.

To run the tests:
  # cd tools/testing/selftests/tc-testing
  # sudo ./tdc.py

You can specify the tc executable to use with the -p argument on the command
line or editing the 'TC' variable in tdc_config.py. Refer to the README for
full details on how to run.

The initial complement of test cases are limited mostly to tc actions. Test
cases are most welcome; see the creating-testcases subdirectory for help
in creating them.
