TFTP transfer size can be used to re-size the TFTP progress bar on single line based on the server reported file size. The support for this has been around from 2019, but it was never converted to proper Kconfig. While adding this new Kconfig, enable it by default for OMAP2+ and K3 devices also.

help
|
|
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.

Selecting this will allow the Ethernet interface to function

A new MAC address will be generated on every boot and it will

not be added to the environment.

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.

Default TFTP window size.

RFC7440 defines an optional window size of transmits,

The default TFTP implementation implies a window size of 1.

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.
