Thank you for contacting Intel.
As of the moment, we do not have firmware update for Intel X520 Series Retail Card as we do not encounter issues with it. The firmware update from Dell* is to fix some issues with the affected adapter models.
Hope I was able to address your concern.
I'm having an issue with my x540-T2 as well. I have 3 of them and the one in the case with the lowest temperatures keeps shutting down. Performance /throughput seems erratic as well. I'd like to try a firmware update or find out the warranty / rma options for it as it is NOT a cheap card.
We do not have firmware update for X540-T2.

I just want to confirm there are no current firmware upgrades for the Intel converged networks adapter x540-t2 as of 10/17/16. I installed the nic in a HPE Cloudline server and want to ensure there is not firmware updates for this adapter. Thanks
