The TPACKET_V3 test code consists of a lot of unecessary macro wrappers that rather obfuscate what members are accessed in what way. So get rid of them and make the code more readable. Also credit Chetan for providing tpacket_v3 example code. Furthermore, get rid of private offset usage, as we do not need it here.

Linux Kernel Selftests The kernel contains a set of "self tests" under the tools/testing/selftests/ directory. These are intended to be small unit tests to exercise individual code paths in the kernel. Running the selftests ===================== To build the tests: $ make -C tools/testing/selftests To run the tests: $ make -C tools/testing/selftests run_tests - note that some tests will require root privileges. To run only tests targetted for a single subsystem: $ make -C tools/testing/selftests TARGETS=cpu-hotplug run_tests See the top-level tools/testing/selftests/Makefile for the list of all possible targets. Contributing new tests ====================== In general, the rules for for selftests are * Do as much as you can if you're not root; * Don't take too long; * Don't break the build on any architecture, and * Don't cause the top-level "make run_tests" to fail if your feature is unconfigured.
