Hi,
You replace the 'unused[52]' field before dhcp_discover with 51 bytes.
While the UEFI spec also defines the EFI_PXE_BASE_CODE_MODE struct in
this way it also specifies that an EFI_IP_ADDRESS is 16-byte buffer
aligned on a 4-byte boundary.
So there should probably be a grub_efi_uint8_t between tos and
station_ip to ensure the correct alignment
