This converts the following to Kconfig: CONFIG_GATEWAYIP CONFIG_HOSTNAME CONFIG_IPADDR CONFIG_NETMASK CONFIG_ROOTPATH CONFIG_SERVERIP CONFIG_UBOOTPATH To do this, we introduce a CONFIG_USE_ form of each of the above and change include/env_default.h to test for that to be set before setting a value. Further, we don't want to stringify the IP address related values as they are now properly strings via Kconfig. Signed-off-by: Tom Rini <trini@konsulko.com>

Some DHCP servers are capable to do a dynamic update of a

DNS server. To do this, they need the hostname of the DHCP

requester.

If CONFIG_BOOTP_SEND_HOSTNAME is defined, the content

Default TFTP block size.

The MTU is typically 1500 for ethernet, so a TFTP block of

1468 (MTU minus eth.hdrs) provides a good throughput with

almost-MTU block sizes.

You can also activate CONFIG_IP_DEFRAG to set a larger block.

config TFTP_PORT

bool "Set TFTP UDP source/destination ports via the environment"

help

If this is defined, the environment variable tftpsrcp is used to

supply the TFTP UDP source port value. If tftpsrcp isn't defined,
|
|
the normal pseudo-random port number generator is used.
|
|
|
|
Also, the environment variable tftpdstp is used to supply the TFTP
|
|
UDP destination port value. If tftpdstp isn't defined, the normal
|
|
port 69 is used.
|
|
|
|
The purpose for tftpsrcp is to allow a TFTP server to blindly start
|
|
the TFTP transfer using the pre-configured target IP address and UDP
|
|
port. This has the effect of "punching through" the (Windows XP)
|
|
firewall, allowing the remainder of the TFTP transfer to proceed
|
|
normally. A better solution is to properly configure the firewall,
|
|
but sometimes that is not allowed.

50 characters total which fits on single line.
