The hotspot ANQP delay test was setting a global delay on all
packets which had some unintended consequences. At the time this
was the only way of simulating the test scenario but now hwsim
supports prefix matching so only the ANQP request/response will
be delayed.
This changes all tests to use the default get_ordered_network behavior
rather than some custom or incorrect logic. Any use of
scan_if_needed=True has been removed since this is now the default.
Also any explicit scanning has been removed for tests which do not
require it (where the default behavior is good enough).
With the addition of connect_bssid/roam very few tests actually
require hwsim. Since hwsim can lead to problems with scan results
its best to have it off by default and have each test that needs
it explicitly turn it on.
Tests which previously turned it off have had that option removed.
Tests that do require hwsim still are vulnerable to scan result
problems, so for these tests beacon_int was added to the hostapd
config which seems to help with reliability somewhat.
After the test-runner re-write many tests were left with
stale options that are no longer used at all. These were
periodically getting removed as changes were made to
individual tests, but its apparent now that a tree wide
removal was needed.
This test occationally failed, and it uses the old style of waiting
for connected on the network object instead of the device object.
The hwsim rule was also moved ahead of the IWD() initializer which
ensures that IWD doesn't scan before the rule can be set/processed.
'Connected' property of the network object is set before the connection
attempt is made and does not indicate a connection success. Therefore,
use device status property to identify the connection status of the device.
