A new MAC address will be generated on every boot and it will not be added to the environment. config NETCONSOLE bool "NetConsole support" help Support the 'nc' input/output device for networked console. See README.NetConsole for details. config IP_DEFRAG bool "Support IP datagram reassembly" default n help Selecting this will enable IP datagram reassembly according to the algorithm in RFC815. config NET_MAXDEFRAG int "Size of buffer used for IP datagram reassembly" depends on IP_DEFRAG default 16384 range 1024 65536 help This defines the size of the statically allocated buffer used for reassembly, and thus an upper bound for the size of IP datagrams that can be received. config TFTP_BLOCKSIZE int "TFTP block size" default 1468 help Default TFTP block size. The MTU is typically 1500 for ethernet, so a TFTP block of 1468 (MTU minus eth.hdrs) provides a good throughput with almost-MTU block sizes. You can also activate CONFIG_IP_DEFRAG to set a larger block. endif # if NET
