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.

62 Default TFTP block size.
Patrick Delaunay1e51f3e2020-04-22 14:18:25 +0200[diff] [blame]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.
