13 help
14 Selecting this will allow the Ethernet interface to function
15 even when the ethaddr variable for that interface is unset.
16 A new MAC address will be generated on every boot and it will
17 not be added to the environment.

46 Default TFTP block size.
Patrick Delaunay421de7f2020-04-22 14:18:25 +020047 The MTU is typically 1500 for ethernet, so a TFTP block of
48 1468 (MTU minus eth.hdrs) provides a good throughput with
49 almost-MTU block sizes.
50 You can also activate CONFIG_IP_DEFRAG to set a larger block.
