Negotiation Failure connecting to SONiC switch

We are trying to connect our ConnectX-6 and ConnectX-7 cards to our SONiC switch, but we are getting a negotiation failure error when they are connected

Assuming you have NVIDIA support entitlement for the adapter cards, please open a support case on our portal and we can then help troubleshoot the issue.
