Details:
When attempting to load a file with a size bigger
than 63 MB over TFTP grub shows this error message:
error: timeout reading `/boot/initrd'.
The problem lies in the blocknumber assigned to each
network packet. TFTP uses only 2 bytes for it, therefore
continuing after the overflow with blocknumber 0.
This overflow happens with a blocksize of 1024 after 63 MB.
(With current git of today f70d5c0701c6edf7f83c2e5ad01d29962b0aabd0)
