82575EB onboard NICs support and teaming in W2012R2

Hi

what is Intel's support plan on the 82575EB onboard NICs?

I have them on 12 Intel S5520HC motherboards.

Are driver updates being made for this nic/mobo?

The drivers provided with windows 2012 R2 work fine but they do not include ANS for teaming.

Any drivers I download for Intel adapters fail to install on windows 2012 R2,  (ie PROWinx64-v18.7.exe, that includeds ANS)

The install fails showing error "no supported adapters found", even though this exact driver package installs fine on this exact server with windows 2012 'R1'.

any info would be helpful!

thanks
