  11config PROT_UDP
  12        bool "Enable generic udp framework"
  13        help
  14          Enable a generic udp framework that allows defining a custom
  15          handler for udp protocol.

  17config BOOTP_SEND_HOSTNAME
  18        bool "Send hostname to DNS server"
  19        help
  20          Some DHCP servers are capable to do a dynamic update of a
  21          DNS server. To do this, they need the hostname of the DHCP
  22          requester.
  23          If CONFIG_BOOTP_SEND_HOSTNAME is defined, the content
  24          of the "hostname" environment variable is passed as
  25          option 12 to the DHCP server.

  27config NET_RANDOM_ETHADDR
  28        bool "Random ethaddr if unset"
  29        help
  30          Selecting this will allow the Ethernet interface to function
  31          even when the ethaddr variable for that interface is unset.
  32          A new MAC address will be generated on every boot and it will
  33          not be added to the environment.

  35config NETCONSOLE

  37        help
  38          Support the 'nc' input/output device for networked console.
  39          See README.NetConsole for details.

  41config IP_DEFRAG
  42        bool "Support IP datagram reassembly"
  43        default n
  44        help
  45          Selecting this will enable IP datagram reassembly according
  46          to the algorithm in RFC815.

  48config NET_MAXDEFRAG

  51        default 16384
  52        range 1024 65536
  53        help
  54          This defines the size of the statically allocated buffer
  55          used for reassembly, and thus an upper bound for the size of
  56          IP datagrams that can be received.

  58config TFTP_BLOCKSIZE

  61        help
  62          Default TFTP block size.
  63          The MTU is typically 1500 for ethernet, so a TFTP block of
  64          1468 (MTU minus eth.hdrs) provides a good throughput with
  65          almost-MTU block sizes.
  66          You can also activate CONFIG_IP_DEFRAG to set a larger block.
  67
  68config TFTP_WINDOWSIZE
  69        int "TFTP window size"
  70        default 1
  71        help
  72          Default TFTP window size.
  73          RFC7440 defines an optional window size of transmits,
  74          before an ack response is required.
  75          The default TFTP implementation implies a window size of 1.
  76
  77config TFTP_TSIZE
  78        bool "Track TFTP transfers based on file size option"
  79        depends on CMD_TFTPBOOT
  80        default y if (ARCH_OMAP2PLUS || ARCH_K3)
  81        help
  82          By default, TFTP progress bar is increased for each received UDP
  83          frame, which can lead into long time being spent for sending
  84          data over the UART. Enabling this option, TFTP queries the file
  85          size from server, and if supported, limits the progress bar to
  86          50 characters total which fits on single line.

  88config SERVERIP_FROM_PROXYDHCP
  89        bool "Get serverip value from Proxy DHCP response"

  91          Allows bootfile config to be fetched from Proxy DHCP server
  92                while IP is obtained from main DHCP server.

  98          Amount of additional time to wait for ProxyDHCP response after
  99                receiving response from main DHCP server. Has no effect if
 100                SERVERIP_FROM_PROXYDHCP is false.
