ConnectX-6 VPI vs ConnectX-6 DE Product Differences

I would like to know the features of the DE(MCX683105AN-HDAT) product, not the difference in the number of physical ports.

Please refer to the ConnectX-6 DE firmware release notes. The following section:

The ‘Known Issues’ section of these release notes contains the same statement, alongside descriptions of some ConnectX-6 DE specific issues:
