Automated hostapd/wpa_supplicant testing with mac80211_hwsim

The mac80211_hwsim-based automated testing framework for hostapd and
wpa_supplicant is getting pretty complete and there is now some
documentation available in tests/hwsim/README to describe the setup and
to provide step-by-step instructions on how to get this running on your
own (only a single Linux device is needed).

http://w1.fi/gitweb/gitweb.cgi?p=hostap.git;a=blob_plain;f=tests/hwsim/README;hb=HEAD

There are now 75 test cases (see the list below) in the repository to
give reasonable coverage on normal functionality and also to test some
protocol level conformance. These test cases are run automatically on
every hostap.git commit and I'm moving more towards using a temporary
pending branch to check for regressions before pushing new commits into
the master branch.

Obviously, it would be even nicer if test coverage were greater and
that's something that I'm pushing towards by adding new test cases for
existing functionality and also trying to do that for all new
functionality added to hostapd and wpa_supplicant. That said, it would
certainly be welcome to receive contributions to extend the existing
test cases and add new ones, so that I'm not the only one coming up with
the tests. This can be done with simple python scripts following the
existing examples in tests/hwsim/test_*.py, so no special knowledge or
skills are needed for this. If you have favorite functionality that you
want to make sure will not regress in future releases, contributing a
test case to verify that part of the system would be a good way to do
that.. ;-)

In addition, this design provides quite convenient environment for
development purposes and I would recommend taking a look at this if you
are working on any wpa_supplicant and hostapd changes (or
cfg80211/mac80211 for that matter). Building the test cases concurrently
with new functionality makes it easy to test the changes during
development and results in have the test cases easily available for
regression testing once finished.

If you are not yet familiar with mac80211_hwsim, you may find it
surprisingly nice environment for early (and in many cases, for more or
less all) upper layer WLAN development. This is how I do most of my work
on wpa_supplicant, hostapd, cfg80211, and mac80211 nowadays and wouldn't
really want to have to survive without this type of environment that
protects me from flaky development platforms and drivers that may not
yet be as robust as one might hope. It's much more convenient to get the
upper layer changes, i.e., pretty much anything above the driver,
completed first before moving to such platforms for testing.
