| 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. |
