fd227b9658
for negotiation of timeout and file size to the tftp protocol. This is required by some firmware like EFI boot managers (at least on HP i2000 Itanium servers) in order to boot an image using tftp. The attached patch implements the RFC, and in doing so also implements RFC2347; a generic tftp option extension. PR: 30710 Submitted by: Espen Skoglund <esk@ira.uka.de>
