I have an unexpected problem with Celestica DX010, I just (few days ago) start the new company network and realized that I don't have link with 100GbE cards at 100GbE speed, 40GbE is working fine (with Mellanox ConnectX-4 100GbE and Mellanox ConnectX-3 40GbE cards), but 100 isn't. Autoneg is not working too yet.

What is funny 100GbE is working fine between Celestica DX010 and another Celestica DX010, same cables or transceivers are working fine too ConnectX-4 100GbE and another ConnectX-4 100GbE (real copy file speed is ~7GB/s on Windows and Ryzen 5000), but Celestica and ConnectX-4 not.

any thoughts how to make it working?

This is my sonic version, issues that I know are:
*No auto-negotiation (hardware is supporting it but OS not)
*Huge delay in status of the connected transceivers

autonegotiation is not supported, depending on your cable (SFP28/QSFP28) it may be KR/KR4 instead of KP/KP4, so you need to set the FEC of the port to RS on the switch, and the network card will automatically recognize the FEC from the switch Without manual setting, you can use mlxlink and mlxcables to do related diagnosis
