- 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 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.
