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.

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:
7b386b703 154c0901c4616( efidisk: move device path helpers in core for efinet) 0c3bfbcca22d21( efinet: skip virtual IPv4 and IPv6 devices when enumerating cards) 3dd85e7da62b( efinet: enable hardware filters when opening interface)
