VMware PSOD with Intel x710 in R630

Hi

After installing DELL branded Intel x710 Network Adapters we are getting Purple Screen of Death's in our 3 Hosts with these cards installed.

A case with VMware brought a solution to update the Firmware to the newest version. Current version: 4.41. Latest Version: 4.53

Unfortunately, we have already installed the latest package from DELL which is 16.5.20 and only has Firmware 4.41 in it.

How do we get the latest version of the Firmware from DELL?

Thanks
Michel
