115 (figuration of the utility, using a config file)
117 * Add single quote support for (old) command line parser

202 which showed "Receiver is not ready" errors when U-Boot was
203 processing the receive buffers slower than the network controller

207 Change behaviour of NetLoop(): return -1 for errors, filesize
208 otherwise; return code 0 is valid an means no file loaded - in this
