config NET_RANDOM_ETHADDR
bool "Random ethaddr if unset"
help
Selecting this will allow the Ethernet interface to function
even when the ethaddr variable for that interface is unset.
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.
