This removes dependency on tcpdump by using an already included test
tool for capturing frames with Ethernet headers. There were some issues
in getting tcpdump working on Ubuntu 19.10, so this seems to be a clean
way of addressing that.

Wait for hostapd to report completion of the connection before going

This verifies mac80211 behavior for Layer 2 Update frame use and other
unexpected frames from a not fully authentication station.

When going through 4-way handshake, the station side reports
CTRL-EVENT-CONNECTED after having sent out EAPOL-Key msg 4/4. The AP
side reports AP-STA-CONNECT after having completed processing of this
frame. Especially when using UML with time travel, it is possible for
the connectivity test to be started before the AP side has configured
the pairwise TK if the test is triggered based on CTRL-EVENT-CONNECTED
instead of AP-STA-CONNECT.
Add explicit wait for AP-STA-CONNECT in some of these cases to reduce
likelihood of reporting failures for test cases that are actually
behaving as expected. This shows up with "dev1->dev2 unicast data
delivery failed" in the test log.
Do the same before requesting reauthentication from the station side
since that has a similar issue with the EAPOL-Start frame getting
encrypted before the AP is ready for it.

Waiting for exactly one second for a one second timeout with
time-travel=inf-cpu is not exactly robust, so increase that wait to be
able to see the last EAPOL-Key TX attempt from hostapd.

Once mac80211 starts reporting the used Association Request frame IEs in
the association event, wpa_supplicant will update RSN supplicant IE
information based on that and that will make the AP reject EAPOL-Key msg
2/4 in this particular test scenario due to the hack of including two
RSN IEs in the Association Request frame. Accept this sequence as a
valid test execution in addition to the previously expected connection
to avoid reporting incorrect failures.

The send_eapol() calls for delivering frames to wpa_supplicant had a
copy-paste bug from the earlier hostapd cases. These were supposed to
use the BSSID, not the address of the station, as the source address.
The local address worked for most cases since it was practically
ignored, but this could prevent the race condition workaround for
association event from working. Fix this by using the correct source
address (BSSID).

Pass the full apdev to the add_ap() function instead of just ifname.
This allows us to handle also remote hosts while we can check
apdev['hostname'], apdev['port'].
This step (7) converts the cases where a local variable is used to store
apdev[#]['ifname'] before passing it as the argument to hostapd.add_ap().

The decrypted copy of a GTK from EAPOL-Key is cleared from memory only
after having sent out CTRL-EVENT-CONNECTED. As such, there was a race
condition on the test case reading the wpa_supplicant process memory
after the connection. This was unlikely to occur due to the one second
sleep, but even with that, it would be at least theorically possible to
hit this race under heavy load (e.g., when using large number of VMs to
run parallel testing). Avoid this by running a PING command to make sure
wpa_supplicant has returned to eloop before reading the process memory.
This should make it less likely to report false positives on GTK being
found in memory.

It looks like it is possible for the GTK to be found from memory every
now and then. This makes these test cases fail. Write the memory
addresses in which the GTK was found to the log to make it somewhat
easier to try to figure out where the key can be left in memory.
