2 # Network configuration
6 bool "Networking support"
11 config BOOTP_SEND_HOSTNAME
12 bool "Send hostname to DNS server"
14 Some DHCP servers are capable to do a dynamic update of a
15 DNS server. To do this, they need the hostname of the DHCP
17 If CONFIG_BOOTP_SEND_HOSTNAME is defined, the content
18 of the "hostname" environment variable is passed as
19 option 12 to the DHCP server.
21 config NET_RANDOM_ETHADDR
22 bool "Random ethaddr if unset"
24 Selecting this will allow the Ethernet interface to function
25 even when the ethaddr variable for that interface is unset.
26 A new MAC address will be generated on every boot and it will
27 not be added to the environment.
30 bool "NetConsole support"
32 Support the 'nc' input/output device for networked console.
33 See README.NetConsole for details.
36 bool "Support IP datagram reassembly"
39 Selecting this will enable IP datagram reassembly according
40 to the algorithm in RFC815.
43 int "Size of buffer used for IP datagram reassembly"
48 This defines the size of the statically allocated buffer
49 used for reassembly, and thus an upper bound for the size of
50 IP datagrams that can be received.
56 Default TFTP block size.
57 The MTU is typically 1500 for ethernet, so a TFTP block of
58 1468 (MTU minus eth.hdrs) provides a good throughput with
59 almost-MTU block sizes.
60 You can also activate CONFIG_IP_DEFRAG to set a larger block.
62 config TFTP_WINDOWSIZE
63 int "TFTP window size"
66 Default TFTP window size.
67 RFC7440 defines an optional window size of transmits,
68 before an ack response is required.
69 The default TFTP implementation implies a window size of 1.
