Many tests waited on the network object 'connected' property after
issuing a Connect command. This is not correct as 'connected' is
set quite early in the connection process. The correct way of doing
this is waiting for the device state to change to connected.
This common code was replaced, hopefully putting to rest any random
failures that happen occasionally.
At some point a stray ';' got added into an autotest in a section
of code that is heavily copy pasted. So in turn nearly all the autotests
have this stray ';' after list_devices (and a few in other places).
Make 3 connections in test EAP-TLS, one with an unencrypted private key,
one with the private key passphrase provided in the provisioning file
and one with the passphrase provided through the agent. Also improve
the scanning logic at the beginning.
Test that the AP interface and the station interface managed by iwd
can actually send and receive ethernet traffic when iwd is in the
connected state. Due to linux routing none of the high level utilities
like ping or arping can be easily used to test communication between
two interfaces of the same machine so use a method based on the
mac80211_hwsim/tools/hwsim_test.c utility in the wpa_supplicant tree
that uses a raw socket to inject unicast and broadcast frames.
Add this check in three tests of different security type connections
that simulate a single AP, and the two roaming tests with two APs.
Check that the station can't communicate with the other AP's interface.
