This uses fragmented IPv4 packets to perfrom (variants of) the test
"ping BP" without needing to run a packet capture on the victim device.
This is accomplished by sending the first IPv4 fragment of a ping
request before authenticating, and the second IPv4 fragment after
authenticating. If the device is vulnerable, it should replay with a
ping response. Note that both ping IPv4 fragments are sent in a normal
non-fragmented Wi-Fi frame.
The test was confirmed to work against a Huawei MRD-LZ1F (Huawei Y6
2019).
There are only supported on Python 3.6 and above. With openwifi we
likely need to support an older Python version.
This patch may be reverted in the future once support for older
Python versions is no longer needed.
This parameter can be used each time a test needs to be delayed before
actually executing it.

Adding a delay before actually executing the test. This can be useful in
all the cases the network stack of the victim is still not ready to
receive packets leading to a timed out test result.

The py dependency in requirements.txt causes a security warning on
GitHub and attracts automated bug hunters (without the hunters verifying
the relevancy of the finding). Avoid this.
Flaws in py: CVE-2020-29651
Vulnerable versions: < 1.10.0
Patched version: 1.10.0
Description: A denial of service via regular expression in the py.path.svnwc
component of py (aka python-py) through 1.9.0 could be used by attackers to
cause a compute-time denial of service attack by supplying malicious input
to the blame functionality.

The updated firmware images assure that the sequence and fragment
number of management frames will not be overwirtten. Previously,
it was only assured that these fields were not overwritten for data
frames.
