  SRU Justification:

  [Impact]

  We have tested PXE boot successfully on the BlueField using grubaa64.efi and grub.cfg but HTTP boot does not work. 
  During HTTP boot, UEFI is able to load the grubaa64.efi but doesn’t load grub.cfg and goes instead into the grub rescue shell.
  From the grub shell, I try to load the grub.cfg file manually, but I get the error shown below.

  configfile (http,192.168.200.1)/grub/grub.cfg
  this doesn't works: error: Fail to send a request! status=0x8000000000000002.

  However it works if I run:
  configfile (tftp,192.168.200.1)/grub/grub.cfg

  This forum discusses a similar issue which points to a grub issue:

  Could you please help investigate this? Or point me to the right
  person?
