Bug description:
  [Impact]
  While the Grub2 patches described in LP#1508893 reduce the TFTP time-out, HP ProLiant m400 servers when booting via UEFI, may still experience TFTP timeouts.

  [Test Case]
  PXE boot a UEFI-based system (d-i or MAAS) and monitor the time it takes for GRUB to download the kernel/initrd. tcpdump will show TFTP timeouts and packet retries, and it can take on the order of minutes to begin running the kernel.

  [Regression Risk]
  The fix is restricted to UEFI-based systems.
