2320ac3349 Don't abbreviate ip(8) arguments in examples and tests
ip(8)'s ability to take abbreviated arguments (e.g. "li sh" instead of
"link show") is very handy when using it interactively, but it doesn't make
for very readable scripts and examples when shown that way.

0ebaac9747 test/perf: Work-around for virtio_net hang before long streams from guest
I didn't have time to investigate the root cause for the virtio_net
TX hang yet. Add a quick work-around for the moment being.

70c05e678e test/perf/passt_tcp: Drop iperf3 window size for host-to-guest tests
With a recent 5.15 kernel, passing a huge window size to iperf3 with
lower MTUs makes iperf3 stop sending packets after a few seconds --
I haven't investigated this in detail, but the window size will be
adjusted dynamically anyway and not passing it doesn't actually
affect throughput, so simply drop the option.

6257a2752e test/perf: Try sourcing maximum scaling frequency from cpufreq
On most recent CPUs, that's a better indication of all-core turbo
frequency, or non-turbo frequency, than /proc/cpuinfo.

7aaff3387a perf/passt_tcp: Don't exceed typical L3 cache sizes with buffers
...we might see misleading rate drops with larger MTUs otherwise.

Get it to work also in nested virtualisation environments.
