Add the needed infrastructure for the Extended Key ID tests, update the tests overriding RSN Capabilities to work with and without Extended Key ID support and add additional interoperability tests for Extended Key ID. When supported by the platform (hwsim) all tests will use Extended Key ID by default while staying backward compatible. Signed-off-by: Alexander Wetzel <alexander@wetzel-home.de> --- There is of course much more we could test here. Especially wlantest is a neglected area so far. But then any tests using it are also working when we use Extended Key ID as it is.
