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.

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.

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.
