Update Intel NIC Firmware

 I needed to update the firmware on some Intel X540-T2 cards that I had gotten for my homelab.  The cards didn't appear to have been updated in some time.

After downloading the latest firmware from Intel, I was struggling on the bootutil update syntax.  I came across this blog post that was quite helpful.

I also found this Intel support article that broke down the syntax and options for the bootutil command.

My cards had both the PXE and UEFI firmware, so I had to use the following:

bootutil64e.efi -UP=PXE+EFI -ALL -File=BootIMG.FLB
