I downloaded the latest Linux driver, i40e-2.9.21.tar.gz and expanded it in /usr/local/src/i40e. Compiling it with "make" seemed to work, but a subsequent "make install" produced an error undefined symbol error for the function "i40e_restore_interrupt_scheme". looking at the function, it's declatarion at the top of the file was there, but the actual function was surrounded by ab "ifdef CONFIG_PM". Looking into that, I could not see where it was defined anywhere, but in several places ut was undefined for one fersion of the Linux kernel or another. Since my kernel is fairly recent and it looks like it was undefined for 2.X kernels, I took a chance and just removed the "ifdef" statement. It then compiled and installed. The driver module is loaded, as confirmed by a calls to "ethtool -i enp94s0f0" and "ethtool -i enp94s0f1" The CentOS Network app says the port is connected, but I cannot ping out and "ifconfig" shows it up but not running. I guess when you hack of driver code to get it to compile you really shouldn't expect it to work perfect. I need to know how to compile this driver correctly. Any ideas Intel?
