Bug description:
  [Impact]
  MAAS commissioning may fail when deploying Xenial images or using grubx64.efi from Xenial due to hardware particularities of some Intel 82599-based network cards. Other network manufacturers may be affected as well. The main failure mode appears to be an infinite re-send of some packets because of an unexpected response from the network hardware.

  [Test case]
  Attempt to netboot on a system with a "82599ES 10-Gigabit SFI/SFP+" network adapter.

  [Regression potential]
  As this affects network in EFI mode; any failure to netboot using EFI should be considered a possible regression. Systems may fail to receive data from the network boot server and terminate the process with a timeout. Another possible failure scenario is to fail to receive complete data over the network, or data corruption.

  ----

  I am using MAAS to commission and install machines. When I attempt to commission a machine with a "82599ES 10-Gigabit SFI/SFP+" network adapter the following happens:
  1) TFTP Request — bootx64.efi
  2) TFTP Request — /grubx64.efi
  3) Console hangs at grub prompt

  If I go into bios and force the adapter above into legacy mode then the machine is able to network boot and run through the commission process.
  1) TFTP Request — ubuntu/amd64/generic/trusty/release/boot-initrd
  2) TFTP Request — ubuntu/amd64/generic/trusty/release/boot-kernel
  3) TFTP Request — ifcpu64.c32
  4) PXE Request — power off
  5) TFTP Request — pxelinux.cfg/01-90-e2-ba-52-23-78
  6) TFTP Request — pxelinux.cfg/71e3f102-bd8b-11e4-b634-3c18a001c80a
  7) TFTP Request — pxelinux.0

  Also, if I disconnect the cable to the adapter above and connect a
  cable to the integrated "I210 Gigabit" adapter which is configured for
  UEFI mode. The machine is able to network boot grubx64.efi and run
  through the commission process.
