This commit adds a generic udp protocol framework in the network loop. So protocol based on udp may be implemented without modifying the network loop (for example custom wait magic packet). Signed-off-by: Philippe Reynes <philippe.reynes@softathome.com> Reviewed-by: Simon Glass <sjg@chromium.org>

Enable a generic udp framework that allows defining a custom

handler for udp protocol.

bool "Send hostname to DNS server"
|
|
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.

help
|

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.

Support the 'nc' input/output device for networked console.

See README.NetConsole for details.

This defines the size of the statically allocated buffer

IP datagrams that can be received.

help
|
|
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.

config TFTP_WINDOWSIZE

|

Default TFTP window size.
|
|
RFC7440 defines an optional window size of transmits,
|
|
before an ack response is required.
|
|
The default TFTP implementation implies a window size of 1.
