31 Some DHCP servers are capable to do a dynamic update of a
32 DNS server. To do this, they need the hostname of the DHCP
33 requester.
34 If CONFIG_BOOTP_SEND_HOSTNAME is defined, the content
35 of the "hostname" environment variable is passed as
36 option 12 to the DHCP server.

42 when the ethaddr variable for that interface is unset. In this case,
43 a random MAC address in the locally administered address space is
44 generated. It will be saved to the appropriate environment variable,
45 too.

82 1468 (MTU minus eth.hdrs) provides a good throughput with
83 almost-MTU block sizes.
84 You can also activate CONFIG_IP_DEFRAG to set a larger block.

100 By default, TFTP progress bar is increased for each received UDP
101 frame, which can lead into long time being spent for sending
102 data over the UART. Enabling this option, TFTP queries the file
103 size from server, and if supported, limits the progress bar to
104 50 characters total which fits on single line.
