# Network configuration

menuconfig NET
bool "Networking support"
default y
if NET
config PROT_UDP
bool "Enable generic udp framework"
help
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.
A new MAC address will be generated on every boot and it will
not be added to the environment.
config NETCONSOLE
bool "NetConsole support"
help
Support the 'nc' input/output device for networked console.
See README.NetConsole for details.
config IP_DEFRAG
bool "Support IP datagram reassembly"
default n
help
Selecting this will enable IP datagram reassembly according
to the algorithm in RFC815.
config NET_MAXDEFRAG
int "Size of buffer used for IP datagram reassembly"
depends on IP_DEFRAG
default 16384
range 1024 65536
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
int "TFTP window size"
default 1
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
bool "Track TFTP transfers based on file size option"
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
bool "Get serverip value from Proxy DHCP response"
help
Allows bootfile config to be fetched from Proxy DHCP server
while IP is obtained from main DHCP server.
config SERVERIP_FROM_PROXYDHCP_DELAY_MS
int "# of additional milliseconds to wait for ProxyDHCP response"
default 100
help
Amount of additional time to wait for ProxyDHCP response after
receiving response from main DHCP server. Has no effect if
SERVERIP_FROM_PROXYDHCP is false.
