rodrigc 9b64106b02 (1) When sending the TFTP RRQ packet to read a file, ... send along the "blksize" option specified in RFC2348, and the "tsize" option specified in RFC2349. Add code to parse the TFTP Option Acknowledgement (OACK) packet as specified in RFC2347. For TFTP servers which support the "blksize" option, we can specify a TFTP Data block size larger than the default 512 bytes specified in RFC1350. This offers greater read performance when downloading files. We request an initial size of 1428 bytes, which is less than the Ethernet MTU of 1500 bytes. If the TFTP server sends back an OACK packet, then use the block size specified in the OACK packet. Most times it is usually the same value as what we request. If the TFTP server supports RFC2348, we will see performance improvements by transferring files over TFTP with larger block sizes. If we do not get back an OACK packet, then we most likely we are interoperating with a legacy TFTP server that does not support TFTP extension options, so default to the block size of 512 bytes. (2) If the "tftp.blksize" environment variable is set, then take that value and use it when sending the TFTP RRQ packet, instead of 1428. This allows us to set different values of "tftp.blksize" in the loader, so that we can test out different TFTP block sizes at run time.
