    _______________________________________________________

Details:


grub_efi_net_config_real() takes the DHCP acknowledge package from the
EFI_PXE_BASE_CODE_PROTOCOL and passes it to grub_net_configure_by_dhcp_ack().
The content might be from IPv4 or IPv6 address negotiation.

Neither of the function seems to tests if the content relates to an IPv4
address negotiation.

Best regards

Heinrich Schuchardt
