I was looking at picking up a few x550-T2 Ethernet adapters. Driver support for Windows Server 2012 R2 is confirmed on these pages:

https://www.intel.com/content/www/us/en/support/network-and-i-o/ethernet-products/000005768.html Intel® Ethernet Adapters Supported in Windows Server 2012 R2*
However, when trying to download the driver from here, I can't find it:
https://downloadcenter.intel.com/product/88209/Intel-Ethernet-Converged-Network-Adapter-X550-T2 Downloads for Intel® Ethernet Converged Network Adapter X550-T2
Where is the 2012 driver?
I'd also like to confirm that the x550-t2 is using the x550-at2 controller as listed below and not the x550-bt2. The bt2 has physical support for 8 pcie lanes versus only 4 pcie lanes in the at2 which is an issue if one doesn't have pcie 3.0 slots. I just want to know the limitations before purchasing.
