auto-t: test for temporary blacklist The simplest way to test this was to create a new AP, where max_num_sta=1. This only allows a single STA to connect to this AP. We connect a device to this AP, then try and connect with another. This results in hostapd failing with DENIED_NO_MORE_STAS, which will cause a temporary blacklist. We can then disconnect both devices, and reconnect the device that previously got denied. If it connects then we know the blacklist only persisted for that earlier connection.

auto-t: updated autotests to use hwsim.get_radio This removes all the duplicated code where the interfaces are iterated and the radio/hostapd instances are created. Instead the two new APIs are used to get each instance, e.g.: hapd = HostapdCLI(config='ssid.conf') radio = hwsim.get_radio('radX')

auto-t: fix testBSSBlacklist There were a number of fixes here. The waits were changed to wait on the device state instead of the network state and hwsim rules were removed after the test as to not interfere with future tests. One of the rules was setting the signal to -10000 wich was causing the ranking to be zero.

auto-t: fix blacklist test timing issues This test fails randomly, and it appears to be due to excessive scanning. Historically most autotests start a dbus scan right away. The problem is that most likely a periodic scan is already ongoing, meaning the dbus scan gets queued. If a Connect() call comes in (which it always does), the dbus scan gets delayed and will trigger once connected, at a time the test is not expecting. This can cause problems with any assumed timing as well as offchannel frames. This patch removes the explicit DBus scanning and instead uses scan_if_needed with get_ordered_networks. The 'all_blacklisted_test' was also modified to wait for scanning to complete after failing to connect to all BSS's. This lets all the networks fully come up (after being blocked by hwsim) and appear in scan results.
