*_packet_pressure_parallel tests are useful for checking for synchronization
errors, but push the practical limitations of the network stack. Failing
these tests is not unreasonable.
*_packet_pressure tests are a little bit less unreasonable, but also
push the practical limitations of the network stack. Hopefully these
will become stable in the near future.
Despite being able to buffer an arbitrary stream of data,
TCP send is still limited by the available buffer space in the
network stack. Errors from TCP send are perfectly reasonable
and should be handled by reducing the buffer that is attempted.
Dynamic buffers gives the network stack the maximum throughput while
still supporting smaller devices. This should expose the largest number
of issues across differently sized platforms.
Additionally, restructured the UDP tests to avoid unintentionally flooding
the recieving side with bad data after failed packets.
Also, added a bit more documentation
A larger buffer gives the network stack the best options for maximizing
throughput. However, the initial buffer size did not fit on small
targets. Resized 8192 -> 1024.
Attempt to maximize the devices bandwidth with an exponentially growing
transaction of random sequences. Also prints the time taken and bandwidth
reached during the tests.
