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).
