Some DHCP servers are capable to do a dynamic update of a
|

DNS server. To do this, they need the hostname of the DHCP
|
|
|
|
|
requester.

Selecting this will allow the Ethernet interface to function even
|
|
|
|
|
when the ethaddr variable for that interface is unset. In this case,
|
|
|
|
|
a random MAC address in the locally administered address space is
|
|
|
|
|
generated. It will be saved to the appropriate environment variable,
|
|
|
|
|
too.

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.

By default, TFTP progress bar is increased for each received UDP

frame, which can lead into long time being spent for sending

data over the UART. Enabling this option, TFTP queries the file

size from server, and if supported, limits the progress bar to

50 characters total which fits on single line.
