This patch set implements several improvements to the xsk selftests
test suite that I thought were useful while debugging the xsk
multi-buffer code and tests. The largest new feature is the ability to
be able to execute a single test instead of the whole test suite. This
required some surgery on the current code, details below.
Anatomy of the path set:
1: Print useful info on a per packet basis with the option -v
2: Add a timeout in the transmission loop too. We only used to have
one for the Rx thread, but Tx can lock up too waiting for
completions.
3: Add an option (-m) to only run the tests (or a single test with a
later patch) in a single mode: skb, drv, or zc (zero-copy).
4-5: Preparatory patches to be able to specify a test to run. Need to
define the test names in a single structure and their entry
points, so we can use this when wanting to run a specific test.
6: Adds a command line option (-l) that lists all the tests.
7: Adds a command line option (-t) that runs a specific test instead
of the whole test suite. Can be combined with -m to specify a
single mode too.
8: Use ksft_print_msg() uniformly throughout the tests. It was a mix
of printf() and ksft_print_msg() before.
9: In some places, we failed the whole test suite instead of a single
test in certain circumstances. Fix this so only the test in
question is failed and the rest of the test suite continues.
10: Display the available command line options with -h
