Unable to get Mellanox ConnectX-5 to connect to network

Hello,

I am having issues getting a Mellanox ConnectX-5 card to connect via ethernet to the network. I am running RHEL 9.0 and have tried reflashing the firmware, configuring the card to use ethernet, and manually installing the OFED drivers.

Output of ifconfig. The IP is what it should be, but I can’t ping that address and I can’t ping anything from that address

I am getting the following message at boot from the mlx5_core driver:
