if NET_LWIP
config LWIP_ICMP_SHOW_UNREACH
bool "Print ICMP Destination Unreachable messages"
default y
depends on CMD_TFTPBOOT || CMD_SNTP
select PROT_ICMP_LWIP
help
Prints a message whenever an ICMP Destination Unreachable message is
received while running a network command that sends requests via UDP.
Enabling this can make troubleshooting easier.
config LWIP_DEBUG
bool "Enable debug traces in the lwIP library"
help
Prints messages to the console regarding network packets that go in
and out of the lwIP library.
config LWIP_DEBUG_RXTX
bool "Dump packets sent and received by lwIP"
help
Performs an hexadecimal & ASCII dump of the data received and sent by
the lwIP network stack.
config LWIP_ASSERT
bool "Enable assertions in the lwIP library"
help
Compiles additional error checking code into the lwIP library. These
checks are related to conditions that should not happen in typical
use, but may be helpful to debug new features.

help
TCP protocol with selective acknowledgements. Improves
file transfer speed in wget.

int "Value of TCP_WND"
default 32768 if ARCH_QEMU
default 3000000
help
Default value for TCP_WND in the lwIP configuration
Lower values result in slower wget transfer speeds in
general, especially when the latency on the network is high,
but QEMU with "-net user" needs no more than a few KB or the
transfer will stall and eventually time out.
config USE_TFTPSERVERIP
bool "Set a default 'tftpserverip' value in the environment"
depends on CMD_TFTPBOOT
help
Defines a default value for the IP address of a TFTP server to
contact when using the "tftpboot" command. (Environment variable
"tftpserverip")
config TFTPSERVERIP
string "Value of the default 'tftpserverip' value in the environment"
depends on USE_TFTPSERVERIP
