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.
16
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.
26
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.
34
35config NETCONSOLE
36	bool "NetConsole support"
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	help
44	  Selecting this will enable IP datagram reassembly according
45	  to the algorithm in RFC815.
46
47config NET_MAXDEFRAG
48	int "Size of buffer used for IP datagram reassembly"
49	depends on IP_DEFRAG
50	default 16384
51	range 1024 65536
52	help
53	  This defines the size of the statically allocated buffer
54	  used for reassembly, and thus an upper bound for the size of
55	  IP datagrams that can be received.
56
57config TFTP_BLOCKSIZE
58	int "TFTP block size"
59	default 1468
60	help
61	  Default TFTP block size.
62	  The MTU is typically 1500 for ethernet, so a TFTP block of
63	  1468 (MTU minus eth.hdrs) provides a good throughput with
64	  almost-MTU block sizes.
65	  You can also activate CONFIG_IP_DEFRAG to set a larger block.
66
67config TFTP_WINDOWSIZE
68	int "TFTP window size"
69	default 1
70	help
71	  Default TFTP window size.
72	  RFC7440 defines an optional window size of transmits,
73	  before an ack response is required.
74	  The default TFTP implementation implies a window size of 1.
75
76config TFTP_TSIZE
77	bool "Track TFTP transfers based on file size option"
78	depends on CMD_TFTPBOOT
79	default y if (ARCH_OMAP2PLUS || ARCH_K3)
80	help
81	  By default, TFTP progress bar is increased for each received UDP
82	  frame, which can lead into long time being spent for sending
83	  data over the UART. Enabling this option, TFTP queries the file
84	  size from server, and if supported, limits the progress bar to
85	  50 characters total which fits on single line.
86
87config SERVERIP_FROM_PROXYDHCP
88	bool "Get serverip value from Proxy DHCP response"
89	help
90	  Allows bootfile config to be fetched from Proxy DHCP server
91		while IP is obtained from main DHCP server.
92
93config SERVERIP_FROM_PROXYDHCP_DELAY_MS
94	int "# of additional milliseconds to wait for ProxyDHCP response"
95	default 100
96	help
97	  Amount of additional time to wait for ProxyDHCP response after
98		receiving response from main DHCP server. Has no effect if
99		SERVERIP_FROM_PROXYDHCP is false.
