RFC 1350 does not mention block count roll-over. However, a lot of TFTP servers implement it to be able to transmit big files, so do it also. Current block size is 512 bytes, so TFTP files were limited to 32 MB. Signed-off-by: Hervé Poussineau <hpoussin@reactos.org> Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com>
