- What I did
Fix "the input device is not a TTY" error reported by 'show lldp' commands when executed via pytest scripts in sonic-mgmt.
resolves Azure/sonic-buildimage#5019
- How I did it
Removed the usage of '-t' docker exec option to not allocate a TTY, while invoking 'lldpctl'.
- How to verify it
Execute 'TestShowLLDP' test cases in test_iface_namingmode.py script in sonic-mgmt.
