John Fastabend 328aa08a08 bpf: Selftests, break down test_sockmap into subtests
At the moment test_sockmap runs all 800+ tests ungrouped which is not
ideal because it makes it hard to see what is failing but also more
importantly its hard to confirm all cases are tested. Additionally,
after inspecting we noticed the runtime is bloated because we run
many duplicate tests. Worse some of these tests are known error cases
that wait for the recvmsg handler to timeout which creats long delays.
Also we noted some tests were not clearing their options and as a
result the following tests would run with extra and incorrect options.

Fix this by reorganizing test code so its clear what tests are running
and when. Then it becomes easy to remove duplication and run tests with
only the set of send/recv patterns that are relavent.

To accomplish this break test_sockmap into subtests and remove
unnecessary duplication. The output is more readable now and
the runtime reduced.

Now default output prints subtests like this,

 $ ./test_sockmap
 # 1/ 6  sockmap:txmsg test passthrough:OK
 ...
 #22/ 1 sockhash:txmsg test push/pop data:OK
 Pass: 22 Fail: 0

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
