Tested on a desktop with i7 CPU, and on a Dell laptop with an i7 CPU. No discernible regressions. I can't determine if it works on a Denverton platform, but I have to assume Intel got it right.

Just to make you aware, there will be patch(es) coming ~WW40 or later to fix the current upstream ixgbe and ixgbevf drivers to work with B0 silicon. We are hoping to get these into the 4.8 kernel before the kernel release, but may have to go through the stable-kernel tree if the fixes do not make the 4.8 kernel release.

All potential patch(es) will be available on patchworks: http://patchwork.ozlabs.org/project/intel-wired-lan/list/ if they are not already there.
