Builds normally if selected. Excludes LwIP from build if unselected, even if it is a
|
|
dependency of a component or application.
|
|
Some applications can switch their IP stacks, e.g., when switching between chip
|
|
and Linux targets (LwIP stack vs. Linux IP stack). Since the LwIP dependency cannot
|
|
easily be excluded based on a Kconfig option, it has to be a dependency in all cases.

This switch allows the LwIP stack to be built selectively, even if it is a dependency.

ESP32 currently supports 25 layer2 receiving buffer, when layer2 buffer

no copy will be sent to layer3 and packet will be dropped in layer2.

Set TCP receive mail box size. Generally bigger value means higher throughput

LWIP_TCP_WND_DEFAULT=14360, TCP_MSS=1436, then the recommended receive mail box size is

|
(14360/1436 + 2) = 12.
|
|
|
|
TCP receive mail box is a per socket mail box, when the application receives packets
|
|
from TCP socket, LWIP core firstly posts the packets to TCP receive mail box and the
|
|
application then fetches the packets from mail box. It means LWIP can caches maximum
|
|
LWIP_TCP_RECCVMBOX_SIZE packets for each TCP socket, so the maximum possible cached TCP packets
|
|
for all TCP sockets is LWIP_TCP_RECCVMBOX_SIZE multiples the maximum TCP socket number. In other
|
|
words, the bigger LWIP_TCP_RECVMBOX_SIZE means more memory.
|
|
On the other hand, if the receiv mail box is too small, the mail box may be full. If the
|
|
mail box is full, the LWIP drops the packets. So generally we need to make sure the TCP
|
|
receive mail box is big enough to avoid packet drop between LWIP core and application.

UDP receive mail box is a per socket mail box, when the application receives packets

application then fetches the packets from mail box. It means LWIP can caches maximum

for all UDP sockets is UDP_RECCVMBOX_SIZE multiples the maximum UDP socket number. In other

|

On the other hand, if the receiv mail box is too small, the mail box may be full. If the

mail box is full, the LWIP drops the packets. So generally we need to make sure the UDP

It is recommended (RFC 4330) to delay the initial request after by a random timeout from 1 to 5 minutes

This option disables this initial delay. Please use this option with care, it could improve

secret with the current time.
