e2aca6e917 auto-t: correctly import Mapping from collections
The current way this was being done was to import collections and
use collections.Mapping. This has been deprecated since python 3.3
but has worked up until python 3.10. After python 3.10 this will
no longer work, and Mapping must be imported from collections.abc.

e44ccf3daa auto-t: Rework spoofing code
Use scapy library which allows one to easily construct and fudge various
network packets.  This makes constructing spoofed packets much easier
and more readable compared to hex-encoded, hand-crafted frames.

2019823443 auto-t: Fix TA/BSSID addresses of spoofed disassoc
The TA/BSSID addresses of spoofed disassociate frames were set
incorrectly.  They should be using the 02:00:00:XX:XX:XX address, but
instead were being converted over to 42:00:00:XX:XX:XX address

197368dcfc auto-t: hwsim.py: set NoVirtualInterface by default
There is really no reason to have hwsim create interfaces automatically
for test-runner. test-runner already does this for wpa_supplicant and
hostapd, and IWD can create the interface itself.

15c0920777 auto-t: hwsim.py: support async radio creation
Adds a new wait argument which, if false, will call the DBus method
and return immediately. This allows the caller to create multiple
radios very quickly, simulating (as close as we can) a wifi card
with dual phy's which appear in the kernel simultaneously.

The name argument was also changed to be mandatory, which is now
required by hwsim.

7123f47f84 test-runner: remove special case for "root" namespace
This was a placeholder at one point but modules grew to depend on it
being a string. Fix these dependencies and set the root namespace
name to None so there is no more special case needed to handle both
a named namespace and the original 'root' namespace.

1a01486170 auto-t: hwsim.py: turn Hwsim into singleton (per-namespace)
This prevents reallocation of new Hwsim classes on each call if one
already exists. This is a bit more efficient on memory.

f6683bab75 auto-t: hwsim.py: convert addresses to 42:* format
mac80211_hwsim has a funny quirk with multiple addresses in
radios. Some operations require address index zero, some index
one. And these addresses (possibly a result of how test-runner
initializes radios) sometimes get mixed up. For example scan
results may show a BSS address as 02:00:00:00:00:00, while the
next test run shows 42:00:00:00:00:00.

Ultimately, sending out frames requires the first nibble of the
address to be 0x4 so to handle both variants of addresses described
above hwsim.py was updated to always bitwise OR the first byte
with 0x40.

8e5a68f407 hwsim: add Rule.remove_all()
There are really no cases where a test wants to remove a single
rule. Most loop through and remove rules individually so this
is being added as a convenience.

e7d941dc3c auto-t: make spoof_frame more robust
Sometimes scan results can come in with a MAC address which
should be in the first index of addrs[] (42:xx:xx:xx:xx:xx).
This causes a failure to lookup the radio path.

There was also a failure path added if the radio cannot be
found rather than rely on DBus to fail with a None path.

The arguments to SendFrame were also changed to use the
ByteArray DBus type rather than python's internal bytearray.
This shouldn't have any effect, but its more consistent with
how DBus arguments should be used.

1b03675002 auto-t: don't clear out rules from hwsim object
This got added in the re-write but a __del__ method was also
added to the Rule class as well. This caused problems if hwsim
cleaned up since it removed the rules, which caused each rule
to call __del__. Since the rule had already been removed there
was no longer a DBus interface which raised an exception.

0036cb976f auto-t: hwsim: wait for method return
It is not safe to assume that the python dbus implementation will
wait for a method to return. The documentation says this with
respect to reply_handler/error_handler:

"If both are None, the implementation may request that no reply is sent"

To stay on the safe side we should always include the error/reply
handlers and wait for the operation to complete.

699b83cb1f auto-t: removed ';' from many autotests
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).

62bdf6c482 auto-t: hwsim fixup
Changed disassociate reason to 0x07 when spoofing a disassociate
frame. This along with 0x06 are the only two reason codes that
should be accepted in an unprotected disassociate frame.

13429f8f2d auto-t: add spoofing frame support to hwsim util
Using the hwsim dbus interface ".Interface" under the radios
object you can now send an arbitrary frame out from that radio.
Two methods have been added, spoof_frame and spoof_disassociate.

d3cf79ed12 autotests: Restore AP beacons after timeout in testFT-PSK-roam
In the beacon loss test try to simulate a periodic communication problem
because we don't support roaming if the AP goes away completely.
2 seconds seems to be enough to consistently trigger the beacon_loss
event without triggering a disconnect by the linux kernel or hiding the AP
from the roam scan.  Also set the RSSI for that AP lower so that it is
not reselected by iwd.
