Guess no one uses telemetry much otherwise should have gotten accepted. There are some python style things could be cleaned up: $ flake8 --max-line-length=100 ./usertools/dpdk-telemetry-tui.py ./usertools/dpdk-telemetry-tui.py:347:5: E125 continuation line with same indent as next logical line ./usertools/dpdk-telemetry-tui.py:397:41: E203 whitespace before ':' ./usertools/dpdk-telemetry-tui.py:398:40: E203 whitespace before ':' ./usertools/dpdk-telemetry-tui.py:399:49: E203 whitespace before ':' ./usertools/dpdk-telemetry-tui.py:399:82: E203 whitespace before ':' ./usertools/dpdk-telemetry-tui.py:539:45: E203 whitespace before ':' ./usertools/dpdk-telemetry-tui.py:540:43: E203 whitespace before ':' ./usertools/dpdk-telemetry-tui.py:580:5: E125 continuation line with same indent as next logical line ./usertools/dpdk-telemetry-tui.py:637:5: E303 too many blank lines (2) Acked-by: Stephen Hemminger <step...@networkplumber.org>
