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.

|

|
If CONFIG_BOOTP_SEND_HOSTNAME is defined, the content
|
|

of the "hostname" environment variable is passed as
|
|
|
|
|
option 12 to the DHCP server.

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.
