[dpdk-dev] [PATCH 0/3] improvements for telemetry script

[Bruce Richardson <bruce.richardson@intel.com>]

Patch 1 fixes errors reported by flake8 in the telemetry python script.
Inspired by the work by Dave Hunt [1] the final two patches look to adjust the
script so that it works nicer when commands come from an input pipe rather than
from an interactive terminal.
