The speedtest-netperf.sh script measures the network throughput while
monitoring latency under load and capturing key CPU usage and frequency
statistics. The script can emulate a web-based speed test by downloading
and then uploading from an internet server, or perform simultaneous
download and upload to mimic the stress of the FLENT test program.
It simplifies tasks such as validating ISP provisioned speeds or setting
up and fine-tuning SQM, directly on the router. The CPU usage details
can also help determine if the demands of SQM, routing and other tasks
such as the test itself are exhausting the device's CPUs.
This script leverages earlier scripts from the CeroWrt project used for
bufferbloat mitigation, betterspeedtest.sh and netperfrunner.sh. They are
used with the permission of the author, Rich Brown.

Remove the limit setting core="unlimited", since this shouldn't be needed
in production use (i.e. non-debug) and on an embedded platform, which is
why it's rarely used by any existing packages.

Add an SPKI pin for Cloudflare to help prevent MITM and downgrade attacks,
as described in RFC7858 (DNS over TLS). The setup of SPKI and the specific
SHA256 certificate hash are taken from Cloudflare's DoT configuration guide
published at https://developers.cloudflare.com/1.1.1.1/dns-over-tls/.
Note that the certificate is valid to March 25th 2020, 13:00 CET, which
provides ample time for issuance of a backup pin to support future key
rollover.

Retain the upstream value since privacy is usually the key user motivation
for using DNS-over-TLS, and simply note that those encountering sub-optimal
routing may consider disabling the setting.

The config file /etc/stubby/stubby.yml is not registered properly and any
local changes are being overwritten on upgrade or reinstall.

The script removes the UCI option ucitrack.@sqm[0] if present and then
returns success. If that UCI option is already absent however, the
script incorrectly returns failure, which blocks upgrade of the
luci-app-sqm package.
