Enable a generic udp framework that allows defining a custom
|
|
handler for udp protocol.

config BOOTP_SEND_HOSTNAME
|
|
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.
|

config NET_RANDOM_ETHADDR
|
|
bool "Random ethaddr if unset"
|
|
help
|
|
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.

|
config NETCONSOLE

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

See README.NetConsole for details.

config IP_DEFRAG

Selecting this will enable IP datagram reassembly according

to the algorithm in RFC815.

|
|
help
|

This defines the size of the statically allocated buffer
|

used for reassembly, and thus an upper bound for the size of
|
|
IP datagrams that can be received.

config TFTP_BLOCKSIZE

int "TFTP block size"
|
|
default 1468
|
|
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

help
|
|
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.
|
|
|
|
config TFTP_TSIZE

depends on CMD_TFTPBOOT
|
|
default y if (ARCH_OMAP2PLUS || ARCH_K3)
|
|
help
|
|
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.

config SERVERIP_FROM_PROXYDHCP

Amount of additional time to wait for ProxyDHCP response after

SERVERIP_FROM_PROXYDHCP is false.

help
|
|
Keeps the server's MAC address, in the env 'serveraddr'
|
|
for passing to bootargs (like Linux's netconsole option). If this is
|
|
enabled, when an ARP reply is received, the server's IP address is
|
|
written there.
|
|
|
|
config UDP_CHECKSUM
|
|
bool "Check the UDP checksum"
|
|
default y if SANDBOX
|
|
help
|
|
Enable this to verify the checksum on UDP packets. If the checksum
|
|
is wrong then the packet is discussed and an error is shown, like
|
|
"UDP wrong checksum 29374a23 30ff3826"

config BOOTP_SERVERIP
|
|
bool "Use the 'serverip' env var for tftp, not bootp"
|
|
help
|
|
Enable this if the TFTP server will be the 'serverip' environment
|
|
variable, not the BOOTP server. This affects the operation of both
|
|
bootp and tftp.
