Hello Alex,

lib/efi_loader/efi_net.c contains pieces of the
EFI_PXE_BASE_CODE_PROTOCOL. But it is incompletely implemented: all
function pointers are NULL and so immediate failure is expected when
using the protocol.

Do you remember why you introduced this protocol into U-Boot?
It is not part of the EBBR specification.

It is not needed for booting via GRUB from disk but seems to be used to
configure the network device in GRUB (grub_net_configure_by_dhcp_ack()
seems only to consume pxe_mode->dhcp_ack).

If the UEFI subsystem is initialized before using the 'dhcp' command the
DHCP results are ignored.

What do you use the protocol for? GRUB?

Best regards
