Continued TFTP timeouts when PXE booting via grub

From comment #11 of LP#1508893:

Looks only the commit 49426e9fd2( efinet: open Simple Network Protocol exclusively) isn't enough, and the
following three commits are required too for grub working well on HP m400 ARM64 server:

      7b386b703154c0901c4616(efidisk: move device path helpers in core for efinet)
      c52ae40570c3bfbcca22d21(efinet: skip virtual IPv4 and IPv6 devices when enumerating cards)
     f348aee7b33dd85e7da62b(efinet: enable hardware filters when opening interface)

This bug was fixed in the package grub2 - 2.02~beta2-32ubuntu1

grub2 (2.02~beta2-32ubuntu1) xenial; urgency=medium

Now grub2 for Xenial just works fine on mcdivitt in case of netboot, especially during loading kernel image
via tftp.

The three grub changes have been tested fine on both APM arm64 board and HP m400, looks
all works fine.

@Ming can you clarify which build(s) you tested (trusty, vivid, and/or wily)? It isn't clear to me if "three grub changes" means you tested all 3 builds, or if you tested one build comprising 3 source changes.

All three have been tested on both two kinds of arm64.

thanks,

I tested this as well as I did not see that Ming had done it. No issues seen.
