If we use netcat to open a socket on linux using wrong IP address, binding
fails as mentioned in the attached picture.

Hi,
Most embedded systems have a power save mode in which memory is shut down
and the state is saved in a non-volatile memory.
Does LwIP have a list of variables that should be saved and restored to
resume proper functionality?

of the result of the ARP request, however raw_input() is
not called unless ip4_input is called and since the arp will be processed
by etharp_input I will not be able to use raw_pcb.

Hi,
The pbuf structure is 16 bytes. Is their a plan to add more elements to it
in the next lwip versions or its size will not be changed?

Hi,
When we receive an echo request using IPv6, LwIP copies the request to new
pbuf to send the reply.
Why LwIP doesn't use the echo request pbuf, instead of allocating a new one
(as what LwIP does when replying to IPv4 echo requests)?
Thanks in advance.

ure only from the lwIP pools, and calls
the MMU to allocate memory to the frame, then I set p->payload to the frame
pointer.
I am able to send and receive ARPs, pings, and DHCP messeages.
Are there specific cases where this procedure will not work correctly?

Hi,
In tcp_write() function, why we don't allocate segments bigger than half
the maximum window we ever received?
Is this a LwIP requirement or TCP protocol requirement?

Hello,
I am using lwip 2.0.3 Release version, I din't find MEMP_SEPARATE_POOLS
Macro. How to know if the pools are placed in one array or separate arrays?

So the LwIP discards such frames, right?

Hello,
In the eth_type enum, I didn't see the ETHTYPE 0x88a8 referring to the TPID
of service-provider outer S-TAG used when the Ethernet frame have double
VLAN tagging.
Does LwIP support Ethernet frames with double VLAN tagging?
Thanks,
Amena

the frame address to clean it.
For the incoming frames, I didn't face any problem in passing the frame
address as pbuf payload ptr of PBUF_ROM type and LwIP did the necessary
parsing of the received frames.

I have to add some instructions inside the LwIP code, right?

LwIP creates a new pbuf RAM 'r' and copies

Indeed I don't want to copy PBUF_ROM payload to the new PBUF_RAM, is there
a way to avoid such copy? why LwIP doesn't copy 'q' to 'r' while preserving
the chain between the PBUF_RAM and PBUF
