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.
