  5. bool "Networking support"
  6. default y

  8. config BOOTP_SEND_HOSTNAME
  9. bool "Send hostname to DNS server"
  10. help
  11. Some DHCP servers are capable to do a dynamic update of a
  12. DNS server. To do this, they need the hostname of the DHCP
  13. requester.
  14. If CONFIG_BOOTP_SEND_HOSTNAME is defined, the content
  15. of the "hostname" environment variable is passed as
  16. option 12 to the DHCP server.
  17. config NET_RANDOM_ETHADDR
  18. bool "Random ethaddr if unset"
  19. help
  20. Selecting this will allow the Ethernet interface to function
  21. even when the ethaddr variable for that interface is unset.
  22. A new MAC address will be generated on every boot and it will
  23. not be added to the environment.
  24. config NETCONSOLE
  25. bool "NetConsole support"
  26. help
  27. Support the 'nc' input/output device for networked console.
  28. See README.NetConsole for details.
  29. config IP_DEFRAG
  30. bool "Support IP datagram reassembly"
  31. default n
  32. help
  33. Selecting this will enable IP datagram reassembly according
  34. to the algorithm in RFC815.
  35. config NET_MAXDEFRAG
  36. int "Size of buffer used for IP datagram reassembly"
  37. depends on IP_DEFRAG
  38. default 16384
  39. range 1024 65536
  40. help
  41. This defines the size of the statically allocated buffer
  42. used for reassembly, and thus an upper bound for the size of
  43. IP datagrams that can be received.
  44. config TFTP_BLOCKSIZE
  45. int "TFTP block size"
  46. default 1468
  47. help
  48. Default TFTP block size.
  49. The MTU is typically 1500 for ethernet, so a TFTP block of
  50. 1468 (MTU minus eth.hdrs) provides a good throughput with
  51. almost-MTU block sizes.
  52. You can also activate CONFIG_IP_DEFRAG to set a larger block.
