* [Ingrasys] update port_config.ini and sfputil for ingrasys platforms - What I did Update port_config.ini on S8810-32Q/S8900-54XC/S8900-64XC/S9100-C32 platforms - How I did it Update alias field and add port field in port_config.ini - How to verify it Check with the "sfputil show eeprom" command. If no error occurs, it is passed. - Description for the changelog Update port_config.ini on S8810-32Q/S8900-54XC/S8900-64XC/S9100-C32 platforms * [Ingrasys] remove debug message in sfputil.py on S8810-32Q - What I did remove debug message in sfputil.py on S8810-32Q - How I did it remove print in get_low_power_mode() and set_low_power_mode() - How to verify it There should be no debug message when executing "sfputil show lpmode" and "sfputil lpmode on Ethernet0"command. - Description for the changelog remove debug message in sfputil.py on S8810-32Q - A picture of a cute animal (not mandatory but encouraged)
