- Why I did it To fix failed test cases of Haliburton platform APIs that found on platform_tests script - How I did it Add device/celestica/x86_64-cel_e1031-r0/platform.json Update functions to support python3.7 Add more functions follow latest sonic_platform_base Fix the bug - How to verify it Run platform_tests script Signed-off-by: Wirut Getbamrung [wgetbumr@celestica.com]
